Description
Performance Suspension Solution. The Bilstein B8 5100 Series Rear Shock for 0.50 to 2.50-Inch Lift is engineered to deliver enhanced ride quality and handling for trucks and SUVs with a rear lift up to 2 inches. This shock absorber provides consistent damping performance and responds dynamically to changing road conditions, improving overall driving comfort and stability.
Construction and Appearance. Built with a durable monotube design, this shock features a zinc-plated finish for corrosion resistance and a smooth body design that does not accommodate coilovers. It includes a black bellows boot and uses high-quality materials such as a 46mm piston and 14mm shaft diameter for reliable operation.
Installation. Designed as a direct fit replacement, installation requires no drilling or special modifications and fits seamlessly with existing suspension setups using eye and stem mounting points.
Warranty and Application. This product includes a limited lifetime warranty for long-term durability and performance. It specifically fits the 2003 to 2024 Toyota 4Runner models without the X-REAS suspension system and accommodates vehicles with rear lifts from zero to two inches.
