KYB Suspension Strut and Coil Spring Assembly P/N:SR4018
Bring back factory ride height and controlled damping with the KYB strut plus assembly (SR4412), a complete strut and coil spring assembly built as the rear left corner unit for the 2008-2012 Toyota Avalon. As an original equipment supplier, KYB engineers the Strut-Plus to help restore the handling and control capabilities your Avalon was designed with, starting from an OE-restoring KYB strut. It arrives pre-assembled with strut, mount and spring, so one part number drops into place for professional results — a big reason KYB complete struts are a go-to for Asian vehicles.

What comes in this KYB strut plus assembly?
It ships pre-assembled with the KYB Excel-G strut, the mount and the application-engineered coil spring, so it installs as one complete unit.
Should I replace both sides at once?
