The Bilstein B8 5165 is a 46mm monotube, gas-charged remote-reservoir shock built for custom off-road and heavy-duty light truck/SUV builds. This unit has 6.3 inches of travel (11.08in collapsed / 17.35in extended), eye/eye mounting with 5/8in eyelets and hourglass bushings on both ends, and 360/80 valving suited to towing and fast heavy-vehicle use. The zinc-plated remote reservoir, connected by a 360-degree swivel banjo fitting, adds oil capacity for greater heat dissipation and more consistent fade-free damping. Sold individually.
