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 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!)

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
