Are shocks included in struts?

Yes, in most contemporary vehicles with MacPherson struts, the strut assembly includes the shock absorber. However, some suspensions use separate dampers that are not part of the strut.

Understanding the terms

Shocks (shock absorbers) dampen movement, converting kinetic energy into heat to control bounce and sway. A strut is a structural suspension component that often houses the damper and springs, serving as both a load-bearing member and a mounting point for steering and suspension parts. In some designs, the strut is an integrated unit that includes the spring and damper; in others, the damper and spring are separate components.

Integrated struts: shocks inside

Before listing the specifics, note that integrated strut designs bundle the spring and damping mechanism into a single unit. This configuration is common in MacPherson struts used on many passenger cars, where the damper is built into the strut housing and the spring sits around it.

• MacPherson strut setups: the coil spring, hydraulic damper, and top mount are packaged together as a single assembly.


• Replacing the strut assembly typically replaces both the spring and the damper, rather than swapping separate components.

In these designs, the shock is not serviced separately; it is part of the strut assembly that’s replaced as a unit when worn or damaged.

Separate shocks: dampers outside the struts

Before listing, consider that some suspensions keep the damper completely separate from the spring and strut. These arrangements are common in multi‑link or double‑wishbone layouts and in various rear suspensions, where the damper is a distinct component.

• Independent suspensions with separate dampers: the coil spring and the shock are mounted as separate parts, so the damper is not included in the strut.


• Rear suspensions in many trucks and SUVs often use separate shocks even when the springs are mounted on a different suspension member.

These configurations require servicing shocks as individual parts, independently of the strut or other suspension components.

How to identify on your vehicle

To determine whether your car uses integrated struts or separate dampers, consult the owner's manual or a parts diagram. Look for terminology such as “strut assembly” (which usually includes both spring and damper) versus references to “shocks” or “dampers” listed separately. Physically inspect the front suspension: if a single unit carries the spring and damper together from the wheel hub to the chassis, you’re likely dealing with an integrated strut. If the spring and damper are clearly separate components, the dampers are not included in the struts.

MacPherson strut indicators

In a MacPherson setup, the strut typically acts as both the structural support and the damping element, with the spring wrapped around the strut. The top of the strut connects to the strut tower in the wheel well, and the lower end attaches to the steering knuckle.

Other designs indicators

In double-wishbone or multi-link suspensions, you’ll often find the coil spring paired with a separate shock absorber mounted at a different point, indicating the damper is not part of the strut assembly.

Maintenance implications

Choosing between integrated struts and separate shocks affects maintenance in practical terms. Replacing an entire strut assembly can simplify service and ensure balanced performance, though it may cost more upfront. When shocks are separate, you can replace individual dampers, potentially lowering replacement costs if only one damper wears out.

Summary

The relationship between shocks and struts hinges on the suspension design. In many modern vehicles featuring MacPherson struts, the strut assembly includes the shock absorber, so shocks are included. In other suspension layouts, shocks are separate components and are not part of the struts. Always verify your vehicle’s specifications or consult its repair manual to determine whether your struts include the dampers on your specific model.

Do you replace struts with shocks?

Monroe recommends that you change your shocks and struts in pairs. If the front left strut has failed and needs to be changed, you should also install a new front right strut. Similarly, if the rear right shock needs replacing, be sure to change the rear left shock.

Does a strut include a shock?

A strut combines several suspension components into one assembly. The parts incorporated include shock absorbers and coil springs. The strut body connects to a steering knuckle attached to a lower control arm and ball joint, and struts replace the upper control arm.

How much does it typically cost to replace shocks and struts?

The total cost for replacing shocks and struts typically ranges from $450 to $1,500, with luxury or performance vehicles potentially costing much more. This price includes both parts and labor, and it's often recommended to replace all four components at the same time to ensure balanced performance. The final cost depends on your vehicle's make and model, the cost of parts, and your location.

Cost breakdown

• Parts: Shocks can range from $80$ 80$80 to $250$ 250$250 per pair, while struts are typically more expensive at $300$ 300$300 to $760$ 760$760 per pair, depending on the type and brand. 
• Labor: Labor costs can range from $150$ 150$150 to $300$ 300$300 per axle. 
• Full replacement: Replacing all four components (shocks on the rear, struts on the front) can total between $500$ 500$500 and $1,500$ 1 comma 500$1,500 for parts and labor. 

Factors that affect the final cost

• Vehicle type: The cost is significantly higher for luxury, sports, or off-road vehicles due to more complex and expensive parts. 
• Location: Labor rates vary by geographic location, so getting quotes from multiple local mechanics can help you find a competitive price. 
• Parts quality: The price will vary based on whether you choose original equipment manufacturer (OEM) or aftermarket parts. 

When to replace shocks and struts

• It is recommended to check them around every 50,000 to 60,000 miles. 
• Signs of worn-out shocks and struts include a bumpy or bouncy ride, fluid leaks, uneven tire wear, and a noticeable "nose-dive" when braking.

Do I have both shocks and struts?

While this is the case, not all vehicles have struts and may use separate springs and shocks in place of them. You can tell whether your vehicle has struts or shocks by inspecting them, checking your owner's manual or asking a trained automotive technician (who can also tell you if they need to be replaced soon).
