Bilstein shocks deliver superior performance from advanced technology. Bilstein's shock bodies are precision formed using a unique seamless extrusion process that provides superior strength. These bodies are then mated with a solid, induction-hardened chrome-plated and polished steel shaft, machined valving components and high quality seals. These gas pressure shock absorbers feature a self-adjusting working piston with spring-steel valving discs that precisely regulates oil flow for optimum compression and rebound control. These features along with several others take the Ranger's existing suspension to the extreme, providing excellent control, precise handling and durable performance in any off-road situation.
