Bilstein 7100 Short Body Reservoir Shock | 360/80 | 34 inch Extended, 19.5 inch Collapsed SKU: BIL88010
Bilstein 7100 Short Body Reservoir Shock | 360/80 | 34 inch Extended, 19.5 inch Collapsed
Product Overview:
We have found with today's softer rear springs the 360/80 valving of these 7100s works great in the rear of Jeeps, Broncos, Land Cruisers etc. Built for demanding off-road conditions, the Bilstein 7100 Short Body Shock with Remote Reservoir is the go-to option for performance-tuned Broncos and custom builds. With 14.5 inches of travel and 360/80 valving, it’s designed to handle anything from fast trail runs to rock-strewn climbs. The monotube gas-pressure design keeps damping consistent while minimizing heat buildup, and the remote reservoir further enhances performance by increasing oil volume and cooling capacity. Whether you’re building a race rig or just want pro-level suspension for your weekend warrior, this shock gets it done—and keeps doing it.
These DO NOT fit stock Bronco mounts. These shocks are intended for customizers and fabricators.

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.

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.
| Spec | 360/80 | 255/70 |
|---|---|---|
| Rebound | 360 – Firm | 255 – Medium |
| Compression | 80 – Firm | 70 – Soft-Medium |
| Best For | Setups requiring stronger rebound control, including higher spring rates and more aggressive off-road use | General trail use and setups where a more compliant ride is preferred |
| Feel | More controlled and firm | Softer and more compliant |
