Strut & Spring Assembly Pair TRQ SCA57086 - 1ASSP00634

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.

Front Strut & Spring assembly
Ordering parts on the 1A Auto Parts Site is always very easy. This particular order was delivered in good time. The parts were exact fit just as viewed online, and they were very easy to install. The ride and handling of my 05 Chrysler 300 is noticeably much better.

awesome parts and value
Struts were more 50% less than advance, autozone and pelican To save even more the shipping is free, Struts weighed about 30 to 40 pounds, but takes about a week.

Great price easy instal!
The price is the best out there, installation only took an hour and a half using hand tools. The hardest part is wiggling the strut out on the driver side. To give yourself a little extra working room on the removal of the old strut just jack up the car a little bit off the jack stand to give yourself that extra 1/4 inch when sliding the strut out of the bottom.

so far so good
Very fast & free shipping. Prices are way better than going to a local parts store. Installation videos are an awesome addition. All in all satisfied so far, rides way smoother-more comfortable than before. Now for the durability/life span test. (Thats why only 4 stars not 5) Def. Recommend 1A auto to others.

O'Reilly's web page has extended, compressed & travel length measurements. What does it mean if one says 25" for extended lenght or 17" length & which one fits for a touring edition?
Jay M on Nov 29, 2017
BEST ANSWER: The length is for the strut fully extended or compressed. This is not where the car normally rides. The only difference in struts on 300,s are for the SRT8 and cars with self leveling. The rest interchange between models
Will these work on the R/T?
Pierre B on Sep 23, 2017
BEST ANSWER: Should be fine, only thing is that it doesn't come with a nut fused into the strut for the bottom bolt so you gottta hit a hardware store for a nut. Look at the struts on the dodge on the bottom and you'll see what I'm talking about. There's a nut that catches the bolt. I've got an RT myself, I got the struts for my brother's Chrysler 300.
