Detailed Description

Unity 15908 is a suspension strut and coil spring assembly engineered for the rear right side of the Lexus RX300 and Toyota Highlander. It is fully assembled before installation, which helps streamline replacement work and supports a direct-fit repair on vehicles equipped for this application. The assembly is listed for 1999-2003 Lexus RX300 rear right, excluding front wheel drive, and 2001-2003 Toyota Highlander rear right, excluding front wheel drive.

Unity Automotive has more than 40 years of aftermarket manufacturing experience and builds suspension components to OEM specifications. Part number 15908 reflects that approach with a complete assembly format intended for straightforward service on the rear suspension. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Rear suspension noise from a worn strut assembly
• Reduced ride control from a fatigued coil spring and strut combination
• Uneven rear ride height on the Lexus RX300 or Toyota Highlander
• Excessive bouncing or poor damping at the rear right corner
• Time-consuming rebuilds when replacing individual suspension components

Installation Notes and Tips

Verify rear right fitment before ordering. This assembly fits 1999-2003 Lexus RX300, rear right, excluding front wheel drive, and 2001-2003 Toyota Highlander, rear right, excluding front wheel drive. Confirm the vehicle’s drivetrain and suspension configuration against the listing details, and compare the compressed, extended, and body lengths to the original unit before installation.

Because this is a fully assembled strut and spring unit, installation is simplified compared with rebuilding a strut from separate components. Always inspect adjacent suspension parts, mounting points, and fasteners during service to ensure the repair is completed correctly.
