Part Details

  • Quantity:   4 Piece Set

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!)

Great Product
My mechanic picked out parts and I ordered and got a great product for low price and fast and free shipping

Good price but lacks quality
Right out the box the rear shock absorbers was not as stiff as the bad leaking oem shock absorber I was replacing. Knowing that they were new I decided to have them installed anyway. I felt every bump as though they were bad. I just replaced both of my rear shock absorbers and front strut assemblys a year later with the recommended oem sach brand and my car rides better. My recommendations pay the extra money to have the factory parts when it comes to shocks.

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 dont hesitate to ask.
Alex P November 14, 2017
i have an 07 CTS with the sport package. I dont mind going to the FE1 soft ride. Will these fit? and are they the same monotube strut design as oem? Thanks

We recommend that you only replace like parts on your vehicle. They may not mount on the vehicle and may cause other issues with different systems on the vehicle. Thanks!
