Its aluminum-bodied remote reservoir uses tunable base valve technology and pairs with an AS2 Series aluminum modular shock body to provide a versatile platform for racers and performance builders. The threaded body design supports coilover applications and can also be used without coilover hardware, helping accommodate a wide range of suspension configurations.\u003cbr\u003eThis Bilstein shock features a monotube internal design, linear piston, clear-anodized aluminum body, and triple-adjustable damping for independent rebound plus high- and low-speed compression control. These adjustment options allow suspension tuning for track conditions, vehicle setup, and driving style. The shock provides 4.79 inches of stroke and extends to 19.17 inches, while the 14 mm shaft and 46 mm piston support responsive damping performance and consistent control during demanding use.\u003cbr\u003eThe AS2-R Series damper includes a spring seat and is configured with 1\/2-inch Heim upper and lower mounts. Spring hardware options include Bilstein components B4-MKT-0001A00 and E4-MSG-0083A00. Pistons, piston bands, and Heim components are sold separately, allowing builders to select upgrade combinations that match their tuning requirements. With modular construction, substantial adjustment capability, and a design focused on maximizing suspension travel, Bilstein part number 33-337890 is a strong choice for competition vehicles requiring flexible, high-performance damper tuning. Boot is not included.
