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, 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.

Ordered parts
This place is incredible. Ordered parts online which said 7-10 day's to ship. I received them in 2 and half days!!! These people are on the ball. Thank you very much for the fast and ACCURATE serivice. I love being fast but accuracy is more important to me. Nothing more frustrating than ordering and waiting, just to receive wrong parts. I will gladly be ordering more from your company in the future. Thanks again 1aauto team!

Ordering parts was never so easy
If you need parts, this is the place. We ordered a pair of the Shock & Spring assembly for our Explorer. The web site was easy to maneuver through. The price was right and the delivery was quick. We had our quality parts within a couple days and were able to get our vehicle back out on the road.
We will most certainly order from this site again! Good quality at a Great price.

How does this brand compare to Monroe?
Damien M on Jun 20, 2017
