Strut & Spring Assembly Front Pair TRQ SCA57089 - 1ASSP00637

Part Details

  • Quantity: Pair
  • Front or Rear Location: Front

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!)

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.
