KYB Suspension Strut and Coil Spring Assembly P/N:SR4256
Get controlled, factory-height handling with the KYB strut plus — the Strut-Plus Suspension Strut and Coil Spring Assembly (SR4452), a pre-assembled front-right corner unit engineered to help restore your vehicle's ride and control. It's a direct-fit replacement for the 2010-2015 Lexus RX350, 2010-2015 Lexus RX450H, and 2010-2013 Toyota Highlander. As an original-equipment supplier, KYB builds this complete strut and coil spring assembly around an OE-Restoring strut so ride height and handling come back toward factory intent.
Winner of the 2018 Best Overall Import Aftermarket Product and KYB's #1 recommended OE replacement choice for Asian vehicles, this pre-assembled corner unit installs for professional results without separate spring compression.

Which vehicles does this KYB complete strut fit?
It's a direct-fit replacement for the 2010-2015 Lexus RX350, 2010-2015 Lexus RX450H, and 2010-2013 Toyota Highlander. Check the Buyer's Guide tab to confirm your vehicle.
Is the SR4452 a left or right strut?
This is the front-right unit. KYB uses left and right part numbers with side-specific design and components, so order the correct side for your vehicle.
Is this a KYB quick strut assembly I can install without a spring compressor?
Yes. It ships as a fully pre-assembled KYB strut plus assembly with the strut, mount, and coil spring together, so no separate spring compression is required.
Do I need to replace both sides?
This listing is for one assembly. Replacing both left and right struts on the same axle as a matched pair is recommended for balanced, even handling.
