Bilstein B8 5165 Remote Reservoir Shock Absorber

The Bilstein B8 5165 is a race-proven remote reservoir shock absorber series built for custom off-road vehicles, lifted trucks, SUVs, and specialty suspension builds that demand performance beyond what standard shocks can deliver. Sharing the same core technology platform as the Bilstein B8 5160 bolt-on remote reservoir line, the B8 5165 is purpose-engineered for universal and custom application fitment — giving serious builders access to Bilstein's motorsport-derived damping technology in a flexible, configurable package.

Key Features:

• Monotube construction with remote reservoir — Bilstein's industry-leading monotube design is paired with a remote reservoir that dramatically increases oil capacity, improving heat dissipation and delivering consistent, fade-free damping under sustained off-road use
• Patented digressive valving technology — provides full damping force across a wide range of surface conditions and speeds, delivering confident control both on- and off-road
• High-pressure nitrogen gas charge — eliminates fluid aeration and foaming for reliable, repeatable damping performance under extreme loads and repeated impacts
• Floating dividing piston located in the reservoir — removes travel restrictions from the shock body itself, enabling greater wheel articulation and increased shaft movement for maximum suspension flexibility
• 360-degree swivel banjo hose fitting — allows flexible reservoir hose routing for clean, low-profile installation across a wide variety of custom suspension configurations
• Zinc-plated body and hardware — engineered to resist corrosion and withstand harsh off-road exposure including mud, water, salt, and trail debris
• Individually tested and precision valved — every unit is built and validated to strict Bilstein performance specifications before leaving the factory
• Reservoir mounting kit and instructions included — everything needed for a complete, proper installation is included in the box

Designed for modified and specialty vehicles where bolt-on fitment is not an option, the B8 5165 series brings race-ready off-road damping technology to custom builds of all types — from rock crawlers and overlanders to pre-runners and expedition rigs.
