Product Description

The KYB SR4453 Front Left Strut-Plus Assembly is a fully assembled suspension unit engineered as a direct OE-style replacement for front left suspension components on select 2010-2013 Toyota Highlander and 2010-2015 Lexus RX350/RX450h models. This complete Strut-Plus assembly combines a gas-charged Excel-G strut, high-grade coil spring, upper mount, protective boot, bump stop, and isolators into one ready-to-install package. The pre-assembled design eliminates the need for separate spring compression, saving installation time and reducing the risk of assembly errors.

Designed to restore proper ride height, damping control, and suspension geometry, the SR4453 helps improve vehicle stability, ride comfort, and handling performance compared with worn or fatigued suspension parts. Its durable construction and precision engineering help ensure long-lasting performance under everyday driving conditions. For optimal balance and consistent driving feel, replacing both front strut assemblies at the same time is recommended when servicing the suspension.
