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 
Pre-Assembled

Pre-assembled, loaded strut & spring assemblies allow for a quicker, safer install than replacing with just bare struts. 

Trouble-Free Install

Trouble-free install includes the matched parts needed to get the job done. New mounts, bearings, springs and hardware will provide a better ride for your vehicle and save you time from not having to do the job again because a used part failed afterwards.

Matched Parts

When you buy the kit pre-built by us, you can be sure that the parts are matched for optimum performance.  Not all shocks and struts are manufactured the same, so mixing and matching can result in fit issues and potentially decrease the life of the parts.

Saves Time & Money

When you buy one of our kits, you not only save money over buying the parts individually, but you also save time having to search for all of the different parts that are correct for your vehicle (because we did it for you!)

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.

WilI need a wheel alignment once I put the new struts in?
Leon B on Mar 19, 2018
BEST ANSWER: I suggest having your wheel alignment adjusted, especially if you plan to keep the vehicle. After installing the strut assembly on my Highlander, my alignment was a bit off. I use Firestone Auto Care which provides a lifetime wheel alignment. Firestone does a good job and they usually do not push me to buy anything else unless I ask.
Who is the manufacturer of these struts?
Alec B on May 14, 2016
BEST ANSWER: We have a few different aftermarket companies build these parts specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle. If you have any further questions, please don't hesitate to ask.
