The Bilstein 5100 Series Shock Absorber designed specifically to help your turbo diesel reach its pinnacle in ride performance, while supplying the correct length shock for your specific lift. A 5100 Series equipped vehicle offers a much more controlled ride compared to the competitors lifted vehicle shocks, allowing you to maintain a similar feeling of comfort and control you have with a stock vehicle.

NOTE: Lift height is suggested by mfg. Due to the many different aftermarket suspension systems it is recommended that a measurement is taken for proper application. A pin to eye shock is measured from the base of the stem where the mounting hardware rests to the center of the eyelet.
