Part Details

  • Quantity:   Pair

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 

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!)

Parts are the exact pieces.
My 2004 Mercury Mountaineer made a bad creeking sound every turn I made and every bump I hit. It was loud and embarrassing. I ordered two front struts thinking that would solve my problem. 1-Aauto sold them in pairs at a unbeatable price! It came in with-in 2 days, free shipping. It was as easy as the 1-aauto youtube video showed it would be. Unfortunately the loud creeking remained, so I looked back online to find parts, I would of saved myself some time and headache if were to go to the 1-Aauto website first. They have a kit that beat all other prices out there, for under $100 the kit included two upper control arms itself with bushings and ball joints attached, and two bottom ball joint. I also went ahead and brought thehub assembly because the old ones had too much play in it,1/4" at least, it also sold in pairs. Free shipping!! It got in 3 days, it probably would of been sooner but it was over the weekend. It was not as easy as the 1-Aauto youtube video made it look. They made it look too easy.I busted my knuckles but I managed. What surprized me is that the parts came with brand new lock nuts, cotter pins and bolts with lock tight on them, even came with new bolts with lock tight for my caliper bracket. The parts was the exact parts as the old ones which made things alot easier. One of my happiest moments is when I lowered my Mountaineer and heard no noise. Its as quiet as a mouse when I now hit a speedbump or make a turn. Yall really help make it easy when it came to ordering these parts and it was a true blessing on my budget. Thank you so much. I already recommend 1-Aauto to a lot of my friends and will not look any other places if I need a part in the future. Thank you.
