Bilstein 25-331721 B8 5165 46mm Monotube Shock Absorber

The Bilstein B8 5165 is a high-performance 46mm monotube shock absorber engineered for trucks, SUVs, and off-road vehicles that demand superior damping performance. This shock features Bilstein's proven monotube gas pressure technology that ensures consistent fade-free performance even under extreme conditions.

Key Features:

• 46mm monotube design provides larger piston area for improved damping control and heat dissipation
• Gas pressure technology prevents aeration and maintains consistent performance
• Velocity-sensitive digressive valving responds instantly to changing road conditions
• Zinc-plated steel body with protective finish resists corrosion in harsh environments
• Triple-C Technology coating (certain applications) on piston rod reduces friction and extends service life
• Self-adjusting deflective disc valving provides optimal control across varying loads

The B8 5165 series is designed as a direct-fit replacement shock absorber that maintains factory ride height while significantly improving handling, stability, and control. Ideal for vehicles used in towing, hauling, or off-road applications where stock shocks fail to provide adequate performance.
