The Bilstein B8 5125 series monotube shock absorber is built for custom and lifted truck applications where direct Bilstein fitment isn't available. It uses a 46mm monotube piston with patented digressive valving and self-adjusting deflective disc valving to react to changing surface conditions. Available in multiple lengths and mount styles with industry-standard 5/8" hourglass bushings, it's aimed at custom suspension builders.
