Shock Absorbers: Bilstein Reservoir Shocks
Bilstein 5165 & 7100 Reservoir Shocks
With an added reservoir, the Bilstein 5165 & 7100 series shocks provide ultimate control of your Bronco even on the harshest terrain. Zinc plated aluminum housing construction and increased oil capacity dissipate more heat assuring long term durability and consistent performance. Heat is one of the major detriments to the performance and longevity of any shock absorber. Conventional twin tube designed shocks trap the heat within the shock body and do not let it adequately dissipate, making them prone to heat build-up, fade and eventual failure. By contrast, BILSTEIN's technically superior, monotube high gas pressure charged design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The remote reservoir creates added capacity for more oil adding to the effectiveness of the monotube design.Bilstein Remote Reservoir Shocks:
- Monotube gas pressure construction
- Self-adjusting deflective disc valving
- High-flow piston reduces harshness
- Remote reservoir increases shock oil capacity
