Shocks vs. Struts: What You Need to Know Before Buying
Shocks and struts both control suspension movement, but a strut also forms part of the suspension's structure. Select the component designed for the exact vehicle and axle. They are not interchangeable alternatives.
What a conventional shock does
A shock damps movement between its mounting points. Springs support the vehicle, while other suspension parts locate the wheel. A typical conventional-shock replacement does not require transferring a spring onto the damper. Coilovers and load-assist designs can require different procedures.
What makes a strut different
A strut combines damping with a structural suspension role. Its brackets, spring-seat arrangement and mounting geometry are application-specific. Strut removal can affect alignment and may involve a spring holding substantial stored energy. It is a different repair from changing a conventional shock.
One vehicle can use both
Many vehicles have front struts and rear shocks. Others use conventional shocks at all four corners. Check the position and suspension design instead of assuming every corner uses the same component. Left and right struts may also have different part numbers.
Compare the repair package
A bare strut normally supplies the damper and housing. A complete assembly adds the listed spring, mount and other components already assembled. An insert is a cartridge for a compatible serviceable housing. Compare what the repair needs and what each listing includes. Electronic damping, self-leveling systems and previous modifications can change the application.

Frequently asked questions
Are struts simply stronger shocks?
No. A strut has a structural role as well as a damping function.
Can my vehicle use both types?
Yes. The suspension design can differ between front and rear.
Does a complete assembly mean all four corners?
No. It describes the components assembled into a unit. Confirm quantity and position separately.
