Product Description

The Bilstein 33-329093 B6 4600 Rear Shock Absorber is engineered as a high-performance upgrade for factory suspension systems on Toyota 4Runner, FJ Cruiser, and Lexus GX models. Utilizing Bilstein's monotube gas-pressure design, this shock delivers consistent, fade-free damping and significantly improves ride control compared to traditional twin-tube OE shocks. It is specifically tuned for each vehicle application, ensuring optimal balance between comfort and handling.

Designed for stock-height SUVs and trucks, the B6 4600 series enhances stability when towing, hauling, or navigating uneven terrain. The digressive piston technology automatically adjusts damping forces based on road conditions, providing firm control during aggressive driving while maintaining comfort over daily commutes. This direct-fit rear shock installs easily using factory mounting points, making it an ideal solution for restoring or upgrading suspension performance without altering ride height.
