Product Details

Unity Automotive has more than 40 years of aftermarket suspension manufacturing experience, and the 15190 strut assembly reflects that focus on OE-style fit and consistent build quality. This rear strut assembly is made for Lexus LS400 applications where the original rear suspension needs replacement, and it is especially relevant for vehicles that do not use air suspension. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 1990-2000 Lexus LS400, rear. Use Unity 15190 when servicing the rear suspension on Lexus LS400 models across the listed years.

Common Issues It Can Address

• Rear ride height loss from a worn strut or spring
• Excessive bouncing or reduced damping control
• Noisy rear suspension operation from aging components
• Uneven rear stance caused by fatigued suspension parts
• Time-consuming assembly work when replacing individual strut components

Installation Notes

Verify rear air suspension exclusion before ordering. Compare the existing strut configuration, mounting points, and vehicle application to confirm the correct Lexus LS400 rear replacement. Because this is a pre-assembled unit, installation is simplified compared with building a strut assembly from separate parts.
