Product Description

The Bilstein 25-331776 is a high-performance B8 5165 remote reservoir shock absorber designed for custom and modified vehicles, especially light trucks and SUVs with lifted suspensions or unique setups. Its 46 mm gas-charged monotube design delivers consistent, fade-resistant damping performance in demanding driving conditions, making it ideal for off-road enthusiasts and builders seeking greater wheel control and suspension travel. The external remote reservoir increases oil capacity for enhanced heat dissipation, helping maintain smooth performance during extended use on rough terrain.

This shock is engineered for universal applications and does not target a specific vehicle make or model. Instead, it provides suspension builders and custom installers the flexibility to achieve the ride quality and travel length they need in specialized setups. Eye-to-eye mounting with standard 5/8" bushings ensures compatibility with a wide range of brackets and mounts. Always verify mounting dimensions and suspension geometry before installation to ensure proper fitment in your project.
