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 
Direct Fit

Fits and functions correctly.  Competitors combine applications to reduce the amount of parts they carry, resulting in: incorrect vehicle height, poor response and an uncomfortable ride.

Rigorously Tested

Made from higher quality materials than the competition. Built to have a longer life in any environment or road conditions.


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.

Matched Parts

Not all shocks and struts are manufactured the same.  Mixing and matching can result in ride quality issues and decrease the life of the parts.

Saves Time & Money

Over buying the parts individually, or having to search different parts that are correct for your vehicle (because we did it for you!)
