There are different kinds of suspension systems, each with its own strengths and weaknesses. Let's explore how these parts work together and why taking care of them is crucial.
A car's suspension system consists of springs, shock absorbers, and linkages that work together to absorb bumps and vibrations for a comfortable ride.
Independent suspension allows each wheel to move separately, enhancing handling and traction, while solid axle suspension connects both wheels for strength.
Regular maintenance, including inspecting and replacing worn-out parts, is crucial to prevent uneven tire wear, bumpy rides, and safety issues.
Understanding how the suspension system works is essential for early problem detection, ensuring smooth car performance, and prolonging vehicle lifespan.
Upgrading the suspension system can improve handling, stability, and comfort, but it's essential to choose the right parts and consider driving style and goals.
Cars have a special system called suspension that helps us drive smoothly and safely. This system has three main parts: springs, shock absorbers, and linkages. They work together to make sure the car stays stable and comfortable.
The springs help absorb bumps in the road. The shock absorbers control how much the car bounces up and down. The linkages connect everything and help transfer weight to the wheels.
In some cars, each wheel has its own suspension system. This is called independent suspension. It helps the car handle better and gives more traction. A good suspension system is important for a car to perform well. It affects how the car handles, how well it grips the road, and how safe it is.
If you understand how the suspension system works, you can spot problems early and keep your car running smoothly. A well-maintained suspension system helps your car last longer and perform better.
Cars have different kinds of suspension systems, which are designed to fit specific vehicle needs and driving styles. The type of suspension system used can make a big difference in how a car performs, how comfortable it is, and how fun it's to drive.
There are a few common types of suspension systems:
Independent suspension lets each wheel move on its own, which helps the car handle better and feel smoother on different roads.
Solid axle suspension connects both wheels together, making it strong and sturdy, perfect for heavy-duty vehicles like trucks.
MacPherson strut suspension is often used in front-wheel-drive cars, and it's lightweight and compact, which helps the car perform well.
There are other types too, like Double wishbone, Leaf springs, Trailing arm, Torsion bars, Coil springs, Axle Suspension, and Sway bars. Each one has its good and not-so-good points, so it's important to understand the differences when picking a car or upgrading the one you have.
A car's suspension system has four main parts that work together to give you a smooth ride. These parts are springs, shock absorbers, struts, and anti-roll bars.
Springs come in different shapes like coils, leaves, or bars. They absorb bumps on the road, making your ride comfortable.
Shock absorbers, also called dampers, help stop the car from bouncing up and down when you hit a bump. They also help hold the car's weight.
Struts provide strength to the car's body and keep the tires in the right position. This helps the car stay stable and handle well.
Anti-roll bars, also known as sway bars, help the car stay steady when you turn a corner. This makes the car easier to control.
Each of these parts plays a vital role in making your ride smooth and stable.
When you're driving, your car's suspension system helps you have a smooth ride. It absorbs bumps and vibrations from the road, making your trip more comfortable. This system has many parts, including springs, shock absorbers, and linkages, that work together to support the car's weight, passengers, and cargo.
The suspension system is important for keeping your car stable and handling well. Here's how it works:
It absorbs energy from bumps, which helps you stay comfortable and in control.
It keeps your tires in contact with the road, which makes your car handle better and corner smoothly.
It supports the weight of your car, passengers, and cargo, making your ride smooth and stable.
Knowing how your car's suspension system works can help you take better care of your car and keep it running well.
A good suspension system is important for a safe and fun drive. It helps you control the car, feel comfortable, and stay safe on the road. When your suspension is working well, it absorbs bumps, keeps the car stable, and helps you steer smoothly. This means you can drive with confidence.
The suspension parts, like springs and shock absorbers, work together to spread the weight of the car evenly. This helps the car handle well when you accelerate, brake, or turn. A smooth ride also means less body roll, and when you hit a bump, the suspension absorbs the shock, making the ride comfortable.
Regular checks are important to find any problems early. This keeps your suspension working well, which improves your car's performance, safety, and lifespan. By taking care of your suspension, you'll have a better, safer, and longer-lasting car.

A faulty suspension system can cause big problems for your car. A good suspension system helps you have a smooth ride. If you know what to look for, you can catch problems before they get out of hand.
Watch out for these signs of trouble:
Also, listen for strange noises like clunking or knocking when you drive over bumps. These sounds can mean your suspension is failing.
If you feel every bump in the road or your ride is rough and uncomfortable, it might be a sign of suspension trouble. If you ignore these signs, it can lead to more damage and make your car run poorly.
Take Care of Your Car's Suspension to Ride Smoothly
Catch problems early to avoid bumpy rides and uneven tire wear. Regular checks keep your car's suspension in top shape.
Inspect and replace worn-out parts like shock absorbers and springs to keep your car running smoothly. Properly inflated tires are a must for even weight distribution, which affects your car's stability.
Lubricate suspension parts to reduce friction and keep them moving smoothly. Managing your car's weight also helps maintain suspension stability and prevents early wear.
When you want to upgrade your car's suspension, think about what kind of car you have, how you drive, and what you want to achieve. This helps you pick the right parts for the best results.
To get it right, remember these important things:
Suspension kits: These include all the parts you need, like springs and shock absorbers, to make the upgrade easy.
Get a pro to install it: If you're making big changes, let a professional do it to make sure it's safe and works correctly.
Make it yours: Choose parts that fit your car, driving style, and what you want to achieve. This way, you'll get the most out of the upgrade.
You're wondering what the fundamentals of a suspension system are. Basically, it's a system of springs, shock absorbers, and linkages that support the vehicle's weight, absorb road impacts, and enhance stability, steering control, and ride comfort.
You'll find there are four main types of suspension systems: independent, dependent, semi-independent, and air suspension, each catering to specific vehicle needs, driving conditions, and ride comfort preferences.
You determine the appropriate suspension for your car by evaluating your driving style, typical terrain, and load capacity, then exploring upgrades for off-road capabilities or increased support, and finally seeking advice from professionals for compatibility.

Topic #10 from our series.
Read on for more expert advice on transforming your Mustang into a high-performance handling machine. This week's topic is all about dampers, one of the key elements to creating a good-handling Mustang. (If you missed the previous episodes, they're posted on our website in the FAQs & Tech Tips section.)
Please note that what we're talking about here are dampers&#;not dampeners. Often misspelled and mispronounced as "dampener," "damper" is the correct term for today's subject, high performance struts and shocks for your Mustang. For the record, a dampener is something that makes something else damp, i.e., moist. If your dampers turn into dampeners you need new dampers.
OK, it's a damper. Why is it called that?
"Damper" comes from the primary function of a shock or strut, which is to control spring oscillation by damping, i.e., calming it down or reducing it. After an initial compression or extension, a spring will vibrate for quite some time unless something damps the oscillation. A damped oscillation is one that fades away to zero over time. A damper, in the case of a late model Mustang in the form of a strut or shock, damps the spring's natural tendency to oscillate. When the strut or shock is well matched to the spring it controls, the spring oscillation will damp to zero very quickly, usually in only one complete oscillation cycle. If your Mustang had no dampers it would bounce uncontrollably while driving down the road, as hitting a succession of bumps would add new spring oscillations on top of the slowly fading oscillations of previous bumps. Not a sexy look, in our opinion, and downright dangerous.
What's the difference between a shock and a strut?
While a shock is primarily a damper, it may also have secondary functions. For example, a shock may also be used to limit suspension droop travel, to limit suspension jounce (bump) travel, or to mount a spring (commonly called a coil-over design).
On the other hand, a strut has an additional function over that of a shock; it's an integral structural link that helps define the suspension geometry. If you remove a strut from the car's suspension, the wheel will flop about as the geometry of the suspension is no longer completely defined. This cannot happen when you remove a shock from the suspension. Struts are made quite robustly because they are structural links and must withstand high bending loads from cornering and braking.
All to present Mustangs left Ford's assembly line with a strut front suspension and shocks in the rear suspension.
How a damper damps
The suspension springs and the car's mass form a resonant system; think of a guitar. Once activated by a bump, like plucking a string, the spring (string) and mass (car or guitar body) will continue to vibrate for a long time unless the energy is more quickly absorbed by a damper. On a guitar, you can stop the vibration by putting a finger on the string you plucked. In a Mustang, the damper works something like that finger to stop the spring from oscillating.
Give me some details on this spring oscillation thing.
Here's the big picture of how a damper does its work: it converts kinetic energy (motion) into heat. In the case of a Mustang, the hydraulic dampers have a piston inside an oil-filled tube. The piston moves up and down as the suspension moves. The piston motion forces hydraulic oil through a number of small holes. As the oil moves it heats up from friction, which dissipates the kinetic energy.
There are many different damper designs. Some of the differences are large, such as monotube vs. twin-tube, gas charged or not, high-pressure gas vs. lower pressure, adjustable damping or fixed. Other differences are small, and include a myriad of little design differences affecting a damper's performance and effectiveness.
What else does a damper do?
Dampers help keep the tires' tread in contact with the pavement. As every Mustang (and driving) enthusiast knows, that's pretty much the most important thing! They control how quickly weight transfers when braking, turning into a corner, and while accelerating (whether out of a fun curve on your commute or during a drag strip launch).
Dampers produce a force based on how fast the shaft moves, so the amount of damping produced is somewhat proportional to the shaft velocity. The damper only produces a force when it's moving. Good dampers will alter the amount of force according to the shaft velocity. The specifics of the valving design and resulting damping at different velocities affect ride quality as well as performance.
How much damping do you need?
The exact amount can be difficult to quantify&#;and more difficult to achieve&#;especially over a range of shaft velocities. Too much damping reduces tire grip and makes ride quality worse. Too little damping leads to vehicle instability because the spring oscillations are uncontrolled. Since both overdamping and underdamping reduce tire grip, getting it right is quite a trick!
If you're up for some technical stuff, in general, the suspension needs more damping forces at low shaft velocities. More damping is required during turning, braking and accelerating, when the velocity of the shafts in the dampers is low (1"-3"/sec). When the car goes over sharp bumps, the shaft velocities are going to be much higher (10"-20"/sec). To maintain decent ride quality, higher velocities require lower damping forces.
Different Damper Designs
Monotube dampers
This design has a single tube mostly filled with oil. A piston rides inside the tube, with the oil on each side. At one end of the tube, separated from the oil by a second piston, is a section containing a high-pressure gas.
The damping is accomplished by the piston moving up and down in the oil, driven by a rod extending outside of the exterior tube. Oil moves through the piston, allowing the piston and shaft to move inside the tube. The oil's movement is carefully controlled by various holes and valves. The piston design and its valves and orifices are what determine the damping characteristics of the strut or shock. Kind of an amazing engineering feat!
The high-pressure gas keeps the oil from cavitating (creating gas bubbles in the oil) in a not-wanted process called foaming. Foamed oil has a much lower viscosity than bubble-less oil and significantly reduces the damping action.
Twin tube dampers
This design has two tubes, one inside the other. The piston rides inside the inner tube. The space between the inner and outer tubes serves as a reservoir for the oil displaced when the shock shaft moves in and out of the damper body. This reservoir can also contain a separate low-pressure gas reservoir. A valve connects the inner cylinder to the outer (reservoir) cylinder.
Just as with a monotube damper, the piston has valves and holes to control oil flow. That determines the damper's characteristics, or how much it damps.

Which is more effective?
Ah, good question. Monotube dampers have better heat dissipation than twin tube dampers because the oil doesn't have to go through as much material and distance to radiate heat into the outside environment. As the damper does more work, the temperature of the oil increases, which lowers its viscosity, which reduces its damping ability. This gives monotube dampers an advantage in high-performance applications, where the damper is worked harder.
Monotube dampers also have larger pistons that allow more fluid to flow through the valve for a given amount of suspension travel. This allows the piston valves to create a damping curve with a better tradeoff between ride quality and handling.
Pro Tip: Dampers have a very large effect on transient handling and ride quality. In fact&#;and most people don't know this&#;they have far more effect on ride quality than springs do!
Two other factors to consider: rebound and compression
Compression
This is when the spring and damper compress, when your Mustang hits a bump, or on the outside of the car when the body rolls during cornering. The spring and corresponding damper compress, allowing the suspension to absorb the bump. As the unsprung mass (tire, wheel, and suspension) moves upward toward the chassis, the damper turns this kinetic energy into heat so the chassis doesn't oscillate in an uncontrolled way in response to the bump. Picture the old beaters you've seen in grocery store parking lots heaving and bouncing up and down as they hit speed bumps. Good dampers prevent that. The compression valving in the damper is designed to keep this oscillation under control.
Rebound
This is when the spring and damper extend in situations such as after compressing to absorb a bump, or when the tire drops into a depression, or on the side of the car toward the inside of the turn when the body rolls during cornering. The unsprung mass (suspension, tires, and wheels) is moving away from the chassis of the car. When the suspension is moving in this direction, the damper is damping the kinetic energy stored in the sprung mass, turning it into heat.
Either way, during compression and rebound, good dampers damp vertical chassis movement to keep spring oscillation to a minimum, keeping the tires on the road and you in control.
Adjustable Dampers
Adjustable dampers have a provision to allow adjusting their damping force level. A damper labeled "SA" has one adjustment (single adjustable). A damper labeled "DA" has two adjustments (double adjustable).
There are two types of SA adjustment. With some dampers the adjustment changes only the amount of rebound force (typical of Koni). With other SA dampers, the adjustment changes both rebound and compression forces at the same time (typical of Tokico). Note: these settings are paired, not independent. With DA dampers, one adjustment is typically for rebound forces and the second is for compression forces. With DA dampers the adjustments are independent of each other.
Adjustable dampers can offer an advantage by letting you tune the transient handling behavior of the car, like if you have a weekend autocross that you're driving to and from. If you know what you're doing, you'll want softer settings on your way to the event to avoid spilling your morning coffee, and more performance-oriented settings while on the course.
However, this type of tuning requires knowledge and time to learn when and how to adjust the dampers. You need to determine what handling behavior you want to change, and then know what you should adjust, at which end of the car, and in which direction. That requires a skill set that many enthusiasts don't need for how they enjoy their Mustangs. Often, fixed dampers are a better solution because they can't be misadjusted, and they just need to damp the springs you're using with them.
Why MM carries only certain dampers
There are many dampers available for late model Mustangs in a wide range of prices, quality, and features. Here at MM we're interested in improved performance, so we ignore the stock-replacement dampers, like those you'll find at your local auto parts store. Among performance-oriented dampers the old saying "you get what you pay for" holds true, but with some surprising exceptions: some manufacturers offer "high-performance" dampers that don't provide anywhere near the performance level advertised. Have no fear: you won't find those on the MM website.
That leads us to why we carry the dampers we do. Our primary requirement is excellent quality, of course, but we also look for whether there are versions suitable for street use and versions for track performance aimed at the amateur racing-on-a-budget enthusiast.
Two favorites, Koni and Bilstein, are excellent for street-driven Mustangs and those taken to open-track events. But many years ago we discovered their limitations for top-level amateur road racing. That moved us to develop our own line of MM Dampers based on Bilstein internal components. With our own dampers, we can offer several versions, each tailored to different uses and their own appropriate spring rates, plus additional features the big manufacturers don't offer.
Note: We also like Tokico. Their D-spec and Illumina series are excellent for street & strip Mustangs. However, they left the U.S. market and the remaining selection of new Tokico dampers is sadly scanty.
And now, back to why MM Dampers are awesome. Seriously.
Damper design isn't easy; if it was, then all manufacturers would be making great products. In reality, there are more sub-par dampers on the market than good ones.
We put a lot of development time into our dampers. Designing and building a good damper requires a ton of work, and they're by far the most difficult part of the suspension system to get right. If your dampers are bad, they can make an otherwise great suspension design handle and ride like an ox cart.
For a damper intended for street use, there's always a tradeoff between good ride quality and good handling. Small differences in the damper design can skew the results too far in one direction, or even ruin both ride quality and handling.
When developing damper valving, the MM engineering team tests prototypes on a damper dynamometer, commonly called a "shock dyno." This machine extends and compresses the damper at varying velocities, while measuring and recording the forces created by the damper. Once we're happy with the dyno behavior, the damper goes onto a Mustang for real-world ride and handling testing.
Here's a generalized example of how the results of a shock dyno test look:
Click on the image for a larger version.
For on-car testing, we use a sophisticated Motec data logging system. This system has suspension travel sensors on all four corners, accelerometers for all three axes', a yaw sensor, and sensors for all the other basics such as throttle position, wheel speed, etc. We analyze the logged data to help design the next iteration of damper valving. Then it's back to the shock dyno. We repeat this process until the results meet our design goals for the ride and handling characteristics we're looking for.
Most MM dampers have fixed valving (check out the dampers listed for your Mustang to see our current offerings). This best suits the needs of most of our customers. Even for many in competitive road racing, the fixed valving provides the best results. Other than matching the MM series to your chosen spring rates, there's no need for any fiddling with damper tuning at the track (or on the street). That lets you concentrate on driving and improving your skills, rather than being a test driver.
You need a unique skill set to be a good test driver, including being able to evaluate the car's handling behavior to decide what changes to make to the dampers, if any. With adjustable dampers, decisions need to be made:You need a unique skill set to be a good test driver, including being able to evaluate the car's handling behavior to decide what changes to make to the dampers, if any.
That's a lot of decisions for an amateur racer. If you're up for it, MM does have very sophisticated high-end DA dampers for some applications, with more to come. At a more modest price level, we recommend Koni SA or DA dampers.
Matching dampers to springs
We've only been talking about dampers, but they're really just half of the important "springs and dampers" component of making a Mustang handle really well. Back in Episode 5 of this series we talked about springs in depth. We always recommend you choose the springs for your Mustang first&#;then get dampers to match. To help you make decisions we have a popular and handy Guide to Choosing Spring Rates and Dampers. The next step is contacting our Tech Associates for advice. For more advanced help, we have a Technical Services option to evaluate your situation and recommend springs and dampers just for your Mustang; choose the "Spring Rate" option.
