Bilstein 7100 Short Body Reservoir Shock | 360/80 | 34 inch Extended, 19.5 inch Collapsed SKU: BIL88010

Bilstein 7100 Series Short Body Shock with Remote Reservoir

14" Travel | 360/80 Valving | 34" Extended, 19.5" Collapsed

When performance matters, the Bilstein 7100 Short Body Shock with Remote Reservoir delivers. With precision valving, 14 inches of travel, and a monotube gas-pressure design, these shocks are made for serious off-roaders, prerunner trucks, buggies, and trail-tuned classics like the Early Bronco. Featuring 360 rebound / 80 compression valving, this model provides strong rebound control with controlled compression damping over rugged terrain and at speed. The remote reservoir increases oil volume and improves heat dissipation to help reduce shock fade during demanding use. If you're building a suspension system from the ground up, WILD HORSES can help design a full kit using these shocks to fit your application.

• Extended Length: 34" | Collapsed Length: 19.5": Ideal for long-travel suspension systems.

• 360/80 Valving: Features 360 rebound and 80 compression valving for strong control of suspension extension with controlled compression damping.

• 14-Inch Travel: Great for lifted vehicles and high-articulation trail rigs.

• Monotube Gas Pressure Design: Superior cooling and consistent damping performance.

• Remote Reservoir: Adds oil volume for reduced heat build-up and improved fade resistance.

• 2-Inch Diameter Shock Body: Increases oil capacity and durability under stress.

• Self-Adjusting Deflecting Disc Valving: Automatically adapts to changing terrain conditions.

• Rebuildable & Serviceable: Designed for long-term use and owner rebuilds.

What makes Bilstein 7100 Remote Reservoir Shocks so great?

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 excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The dividing piston also permits the oil to expand as heat builds, preventing aeration (foaming) and viscosity loss. This allows the shock to maintain full damping characteristics as temperatures rise. The remote reservoir creates added capacity for more oil, adding to the effectiveness of the monotube design.

Serious shock for serious off-roaders—Bilstein’s 7100 with reservoir delivers max travel, fade-resistant control, and performance valving for rugged terrain.

What is the difference between 360/80 Valving and 255/70 Valving?

The performance difference between 360/80 and 255/70 valving in Bilstein shocks—specifically the 7100 Series—comes down to how strongly the shock controls rebound and compression. Bilstein lists the rebound value first and the compression value second.

• 360/80 = 360 rebound / 80 compression
• 255/70 = 255 rebound / 70 compression
• Rebound Damping (360 vs. 255)
  • 360 Valving is firmer. It provides greater resistance as the shock extends after compression, helping control spring energy, body movement, and suspension bounce.
  • 255 Valving is softer. It allows the suspension to extend more freely and can provide a more compliant feel depending on vehicle weight, spring rate, and suspension setup.
• Compression Damping (80 vs. 70)
  • 80 Valving is firmer. It provides slightly more resistance as the shock compresses, helping control suspension movement through bumps and impacts.
  • 70 Valving is softer. It allows the shock to compress somewhat more easily for a more compliant response over bumps and uneven terrain.
