Vehicle Fit

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 

To ensure the vehicle performs safely and as designed, we recommend replacing shocks & struts in pairs. If the damping rates are significantly different from side to side (like using different brand parts or mixing old with new) the vehicle body and wheel movement variations could cause handling irregularities. We also recommend performing an alignment after replacement. This will ensure proper tracking and protect your vehicle's tires from premature wear.

Pre-Assembled

Loaded strut & spring assemblies allow for a quicker, safer install than bare struts.  No spring compressor required! 

Trouble-Free Install

Includes the matched parts needed. New components over reused parts provide a better ride and save you from having to repair again.
