Bilstein 7100 Short Body Shock with Reservoir - 360/80, 27.75' Ext, 16' Comp SKU: BIL88129

Bilstein 7100 Series Short Body Shock with Remote Reservoir

11.75" Travel | 360/80 Valving | 27.75" Extended, 16" Collapsed

When performance matters, the Bilstein 7100 Short Body Shock with Remote Reservoir delivers. With precision valving, 11.75 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 a 360/80 custom valving, this model provides controlled compression and rebound performance over rugged terrain and at speed. The remote reservoir boosts oil volume and heat dissipation—making fade a thing of the past. 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: 27.75" | Collapsed Length: 16": Ideal for long-travel suspension systems.

• 360/80 Valving: Tuned for high-performance off-road driving with aggressive rebound/compression control.

• 11.75-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 the 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-free control, and custom 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 the shock resists compression and rebound. These numbers represent the valving force in Newtons, and the first number is compression, while the second number is rebound.

• 360/80 = 360N compression / 80N rebound
• 255/70 = 255N compression / 70N rebound
• Compression Damping (360 vs. 255)
  • 360 Valving is firmer. It provides more resistance to compression, ideal for heavier vehicles, higher-speed off-road use, or setups where control under load and bottoming resistance are critical.
  • 255 Valving is softer. This is better for lighter setups, slower off-road use, or for those prioritizing comfort over aggressive performance.
• Rebound Damping (80 vs. 70)
  • 80 Valving is firmer. It slows the shock extension a bit more, offering better control and reduced bounce—especially useful when the springs are stiff or the terrain is fast and rough.
  • 70 Valving is softer. It allows the shock to extend faster, giving a more responsive feel and a softer return after compression.
