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.

  • OE-Restoring build: Includes a KYB Excel-G strut with a stronger steel outer shell and KYB's application-specific, precision-designed damping valves.
  • High carbon steel coil spring: Developed around the vehicle's attributes and corner weights to help keep ride height within OE specifications without sacrificing ride quality.
  • Safety-system aware: Engineered to help vehicles equipped with electronic safety systems (ESC, ABS, etc.).
  • Side-specific & USA-assembled: Left and right part numbers with side-specific design and components; assembled in the USA. Winner of Best Overall Import Aftermarket Product.

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.

Frequently Asked Questions

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.
