Product Description

The Bilstein 33-230375 is a universal B8 5125 Series monotube shock absorber engineered for custom suspension applications where a direct Bilstein vehicle fitment isn't available. Featuring a high-gas pressure monotube design with self-adjusting deflective disc valving, this shock delivers consistent, fade-free damping across varied conditions - making it suitable for lifted truck builds, aftermarket suspension projects, and bespoke setups.

Finished with a corrosion-resistant zinc-plated smooth body and equipped with a stem-to-eye mount configuration, this shock offers approximately 11.25" of travel and installs flexibly when matched with compatible mounting hardware. The included black protective bellows boot helps shield the shaft from debris. Because this shock is universal, proper installation requires matching its length and mounts to your specific suspension geometry or using suitable adapters.
