Product Description

The Bilstein 33-230412 is a universal B8 5125 Series monotube rear shock absorber engineered for custom suspension applications and lifted truck builds where a direct vehicle-specific part does not exist. Its high-gas pressure monotube construction with self-adjusting deflective disc valving provides consistent, reliable damping performance and improved control over many stock design shocks. Built with a zinc-plated smooth body, this shock offers enhanced corrosion resistance for demanding conditions.

Featuring a stem-to-eye mounting configuration with industry-standard 5/8" lower eye and approximately 9.22" of travel, this shock offers flexibility for a variety of custom suspension geometries. The included black protective bellows boot helps shield the shock shaft from debris. Because this shock is universal, proper fitment requires matching its length and mount type to your specific suspension setup or using suitable adapters. It's an ideal choice for suspension builders and off-road enthusiasts seeking consistent performance and control in bespoke or aftermarket builds.
