Product Description

The Bilstein 33-186504 is a **universal B8 5125 Series monotube shock absorber** engineered for custom suspension applications and lifted vehicles where direct vehicle-specific shocks are unavailable. With a high-gas pressure monotube design and self-adjusting deflective disc valving, this shock delivers consistent, fade-free damping and improved control across varied conditions compared to many standard replacement shocks. Its compact size and ~6.64" travel make it suitable for bespoke suspension setups requiring shorter shock travel.

Finished with a corrosion-resistant zinc-plated smooth body and equipped with a stem-to-eye mount configuration using industry-standard 5/8" bushings, the 33-186504 shock offers flexibility for a range of custom uses. The included black protective bellows boot helps shield the shock shaft from debris. Because this product is universal, proper fitment requires matching the shock's overall dimensions and mounting type to your specific suspension geometry or using appropriate adapters and hardware. This universal shock is ideal for suspension builders, off-road enthusiasts, and aftermarket projects looking to upgrade or customize damping performance.
