Product Description

The Bilstein 25-331769 is a universal high-performance remote reservoir shock from the B8 5165 Series, engineered for custom off-road and lifted vehicle suspension applications where direct vehicle-specific parts aren't available. Featuring a high-gas pressure monotube design and a remote reservoir that increases oil capacity, this shock delivers consistent, fade-free damping even in demanding off-road conditions, improving control and durability compared to standard shocks.

Its 46 mm monotube body and approximately 14.1" of travel make it well suited for custom light truck and SUV builds, while the 360° swivel banjo fitting on the reservoir hose allows flexible mounting options in tight suspension layouts. The zinc-plated body enhances corrosion resistance, and the eye-to-eye mount configuration with 5/8" bushings simplifies installation. Because this shock is universal, matching it to your suspension geometry or using appropriate adapters and hardware is required for proper fitment.
