• Application specific design: These parts are built to match the original fit for 2001-06 Lexus LS430 rear driver and passenger sides, which means no modifications are required for direct replacement.
• Matched pair delivery: Both left and right rear assemblies are included in the two-piece kit, ensuring balanced performance and more consistent handling after installation.
• Restored ride performance: Calibrated shocks and quality coil springs are intended to reduce body sway and vibration for improved comfort on rough roads.
• Comprehensive component set: Each unit includes bearing plate, spring isolators, upper spring seat, coil spring, boot kit, and premium strut so the replacement is complete.

Who It's For

This kit is best for Lexus LS430 owners from model years 2001 through 2006 who want a direct-fit, full rear shock and spring replacement without sourcing separate components. It suits experienced DIYers and independent shops that value assemblies arriving pre-loaded and ready to install.
