Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Springs hold the car up and set its ride height. Worn suspension and steering parts show up as clunks, wandering, uneven tire wear and a vague feel; fresh parts restore control, and performance parts sharpen it.
Installation & tips
- Use shocks in good condition with new springs and get an alignment after.
- Shocks: Springs work best with healthy dampers.
- Alignment: Ride height changes alignment.
- This part affects how the vehicle stops, steers or holds the road. If you are not sure how to fit it, have it installed or checked by a qualified mechanic.
