Product Description

The Bilstein 33-230443 is a universal B8 5125 Series monotube shock absorber engineered for custom suspension applications and lifted truck builds where a direct vehicle-specific part is not available. Its high-gas pressure monotube construction combined with velocity-sensitive, self-adjusting deflective disc valving delivers consistent, reliable damping performance across diverse conditions, making it suitable for aftermarket suspension projects and bespoke setups.

Featuring a zinc-plated smooth body for enhanced corrosion resistance and an eye-to-eye mount configuration with standard 5/8" bushings, this shock offers approximately 12.6" of travel for flexible installation in custom suspension geometries. The included black protective bellows boot helps protect the shaft from debris. Because this shock is universal, proper fitment requires matching its length and mounting type to your specific suspension setup or using appropriate adapters and hardware. It's an excellent choice for suspension builders and automotive enthusiasts upgrading damping performance in lifted or custom vehicle builds.
