Rear Strut Kit for Lexus LS430

This Unity kit supplies two fully assembled rear strut assemblies for the 2001 to 2006 Lexus LS430. Each unit arrives with the strut, top mount, bearing plate, bumper, insulators and coil spring already fitted. The design targets owners and technicians who want a complete corner replacement without sourcing individual components.

Replaces Worn Original Suspension

The kit directly substitutes the factory rear struts that have lost damping control or suffered spring sag over years of service. Installing both sides together restores balanced handling, ride height and braking stability in a single job. The improvement is most noticeable when the original units have exceeded their service life or show visible leakage.

Bolt-On Installation With No Special Tools

Because every component is preassembled, the repair proceeds with standard hand tools and a floor jack; no spring compressor is required. The most common issue is seized lower mounting bolts or corroded knuckle bores, so applying penetrating oil beforehand and allowing soak time prevents rounded fasteners. Torque all fasteners to the vehicle manufacturer’s specification after installation.
