KYB Suspension Strut and Coil Spring Assembly P/N:SR4140
Help return your 2014-2019 Toyota Corolla to its original ride height and handling with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly, MPN SR4645, a pre-assembled KYB strut assembly. It drops in as a pre-assembled, direct-fit replacement for the rear-left corner of the 2014-2019 Toyota Corolla, pairing an OE-Restoring KYB Excel-G strut with a matched coil spring so there's no spring compressor to wrestle with.
A strut assembly carries vehicle weight, sets ride height, serves as the steering pivot, and helps control vehicle stability. As an original equipment supplier, KYB engineered the Strut-Plus to help restore the handling and control of your 2014-2019 Toyota Corolla.
As one of KYB complete struts, this KYB quick strut assembly is sold individually for the rear-left position; for balanced ride and handling, replacing the opposite rear side at the same time is recommended.
What is the KYB SR4645?
It's a KYB Strut-Plus complete strut and coil spring assembly (MPN SR4645) — a pre-assembled unit combining a KYB Excel-G strut, high carbon steel coil spring, and mount for the rear-left corner.
What vehicle does the SR4645 fit?
It's a direct-fit replacement for the rear-left corner of the 2014-2019 Toyota Corolla. Check the Buyer's Guide tab to confirm it matches your vehicle.
Which corner does this KYB strut plus assembly cover?
The rear-left position. KYB uses left- and right-specific part numbers with side-specific design and components, so order the correct side for your vehicle.
Do I need to replace both sides?
It's sold individually for the rear-left corner. Replacing the opposite rear strut at the same time is recommended for balanced, even ride and handling, though it isn't strictly required.
Do I need a spring compressor to install it?
No. The Strut-Plus arrives fully pre-assembled with the strut, spring, and mount, so no spring compressor is needed for this rear-left unit.
