Bilstein B8 8125 Series 46mm Monotube Coilover Shock - 23in Extended / 15in Collapsed (33-225500)

The Bilstein B8 8125 series is a professional-grade coilover engineered for custom off-road suspension builds and serious enthusiasts. This 46mm monotube shock is designed for use with dual-rate springs, providing the precise dampening control required for high-speed desert runs and technical rock crawling.

Built to withstand harsh environments, it features a competition-style 3-stage seal pack and a 22mm hard chromed, case-hardened piston rod that resists tensile stress and debris pitting. The remote reservoir and high-temperature hose increase oil capacity to ensure consistent, fade-free performance during periods of intense cycling and heat soak. The zinc-coated threaded body allows for rapid ride height adjustments and easy spring changes.
