Replacing struts used to require specialized tools to compress, remove, and transfer the old spring and mount. Our Pre-assembled, complete strut & spring assemblies come with all new parts and make the job much quicker and easier for the do-it-yourself mechanic.
Strut & spring assembly contains:
Upper Strut Mount
Strut Bearing
Coil Spring
Boot & Bumper Kit
Gas-charged Strut
Install Tip: To keep your vehicle operating safely and as designed:
Replace your shocks & struts in pairs. This will avoid mixing parts (old and new or brands). Mixing parts can cause variations in movement between the vehicle’s body and wheel, resulting in handling irregularities.
Have an alignment performed after replacing your shocks and struts. This will ensure proper tracking and protect your vehicle’s tires from premature wear.

★★★★★August 8, 2019
On time as promised, perfect fit as promised, quality part as promised.
I am extremely pleased with this and all prior purchases from 1aauto. As usual, when needing a part, I always want it yesterday, however, given that the price was less than half what it would have been at the local parts stores, I was more than willing to wait a couple days to save over $100.00

There are more coils on the new springs than was on the original struts, will this make a difference?
The amount of coils should not make a difference in the fit.
