In the past, replacing struts required specialized tools to compress, remove and transfer the old spring and mount.  Pre-assembled with all new parts, our complete strut and spring assemblies make this job much quicker and easier for the do-it-yourself mechanic.

Each complete strut & spring assembly contains:

  • Upper Strut Mount
  • Strut Bearing
  • Coil Spring
  • Boot & Bumper Kit
  • Gas-charged Strut 

Lifetime Warranty

This item is backed by a Limited Lifetime Warranty. In the event this item should fail due to manufacturing defects during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser. Please keep your invoice for proof of this warranty.

  1. step : Remove the shock absorber (0:29)
    • It is recommended to raise and secure the vehicle, but it is possible to do this with the vehicle on the ground.
    • Remove the 18 mm bolts at each of the strut by securing one end of the bolt with the wrench and use the socket and ratchet to remove the bolt from the nut.
  2. step : install the new shock (3:09)
    • Insert the shock into its mount and thread the bolt though.
    • Repeat with the bottom end of the strut.
    • Tighten the nut and bolts with your socket and ratchet and wrench
