The B8 5100 is a 46mm monotube shock valved for square-body 4WD trucks and SUVs running 3 to 4 in of rear lift, with a velocity sensitive digressive piston that firms up over sharp hits and stays compliant across small surface texture. The monotube construction keeps gas and oil apart so damping holds up when the rear axle is working hard on washboard, trail or a long grade. It measures 16.14 in collapsed and 26.15 in extended, mounts to a cantilever at the top and a 14.4mm eye at the bottom, and ships with a black bellows boot over the shaft. The body is zinc plated and the shock is made in the USA.
