Coilovers vs. Shocks vs. Struts: Understanding the Differences and Benefits

How do shocks and struts work? The suspension system of a car includes crucial parts like shocks and struts. These componencharge of maintaining the car’s comfortable ride and keeping its wheels on the ground.Shocks are hydraulic dampers that regulate suspension movement by soaking up spring energy during compression and rebound.

How does Coilover work?

The following are the main difference between coilovers, shocks, and struts:

  • Design: Unlike shocks and struts, which are separate components, coilovers combine the shock absorber and spring into a single unit.
  • Adjustability: Coilovers allow drivers to fine-tune the suspension settings (Ride Height, Damping Adjustment, replaceable Spring races), while shocks and struts are not typically adjustable.
  • Application: In contrast to shocks and struts, are more regularly seen in regular cars, coilovers are generally used during high-performance driving, road racing drifting, and car show.
  • Installation: The Installation shocks and struts are a very similar process, but coilovers require a bit more adjustment prior to installing (Ride Height & Spring Tension)
  • Cost: Due to their tunable and high-performance construction, coilovers are typically more expensive than factory / shocks and struts.
  • Function: While coilovers enhance driving, car design and vehicle performance, shocks and struts are designed to give a smooth and safe ride on the road.
  • Maintenance: Coilovers vs. Shock& Struts need to both be maintauned regularly.. Shocks and struts provide a smooth and stable ride for regular driving. In contrast, coilovers offer a more customizable and high-performance suspension option for those wishing to improve handling and performance on the track. Individual driving preferences and the vehicle configuration ultimately determine which suspension system to use: coilovers, shocks, or struts.

Here’s a summary of the key takeaways:

What is a coilover?

A coilover is a suspension assembly that places a coil spring with a damper. The spring supports the vehicle and compresses as the wheel moves; the damper controls how that movement slows and returns. Because the spring and damper are supplied together, a coilover kit can be designed as a matched unit for a specific vehicle application. Its mounts, spring and adjustment features vary by product.

The word “coilover” describes the assembly, not one universal setup. Some vehicles use a strut-type layout, while others keep a separate spring and damper at one axle. A performance kit may allow ride-height or damping adjustment, but those features are product-specific. Check the exact year, make, model, mounting details and included hardware before comparing kits, and follow the product instructions during installation and setup.

PartTypical arrangementWhat it doesWhat to consider
CoiloverCoil spring paired with a damper as an assemblySupports the vehicle through the spring and controls suspension movement through the damperKit fitment, mounts, spring/damping specifications and adjustment range are product-specific
Shock absorber (damper)Often separate from the coil spring on vehicles with a separate spring-and-shock layoutControls spring and suspension movement; the spring carries the vehicle loadMatch the replacement to the vehicle, mounting and suspension layout
StrutDamper integrated into a structural suspension assemblyControls movement and contributes to locating/supporting the wheel assemblyConfirm the vehicle-specific assembly and follow alignment guidance after replacement

These terms describe related but different parts. A coilover can use a strut-style layout, so compare the exact product and vehicle application rather than relying on the name alone.

Frequently asked questions

Are shocks and struts the same thing?

Both use a damper to control suspension movement, but a strut is also part of the suspension structure and wheel-location assembly. The exact layout depends on the vehicle.

Can coilovers replace any shock or strut?

No. Coilover kits are application-specific assemblies. Confirm the vehicle year, chassis, mounting points and product notes before treating a kit as a replacement for another suspension part.

Do all coilovers adjust ride height and damping?

Adjustments depend on the product. Read the selected kit details and instructions to see which settings are included; do not assume every design has the same controls.

How should I choose between coilovers and replacement shocks or struts?

For restoring a factory-style setup, start with replacement parts specified for the vehicle. Choose a coilover kit when its application and adjustment options fit your goals, and plan to follow the installation and alignment instructions.
