Gladiator JT 2020-2025 Jeep 4WD - Bilstein REAR Adjustable B8 8100 (DSA) Series Shock (fits w/2-4.5" Rear Lift)

The Bilstein B8 8100 (DSA) 25-331103 is a premium, large-bore reservoir shock absorber engineered for lifted Jeep Gladiator JTs that demand superior damping, heat control, and tunability across all terrains. Built from aerospace-grade billet components, this advanced 60mm (2.65") shock delivers exceptional oil capacity and thermal stability, making it ideal for high-speed off-road driving and long-distance rough-road performance.

At the heart of the B8 8100 is Bilstein’s Dual Speed Adjustment (DSA) system, featuring easy-to-use clicker knobs that independently control low- and high-speed compression damping. This allows drivers to fine-tune the shock’s behavior for technical rock crawling, washboard trails, or smooth highway cruising—all with precise, tool-free adjustment.

The monotube design ensures fade-free damping consistency, while velocity-sensitive digressive valving is specifically tuned for optimal control and comfort in each application. Paired with its oversized 60mm piston and either a remote or piggyback reservoir configuration, the B8 8100 maintains cool operating temperatures and steady performance under extreme loads. With extended travel, high-strength 18mm shafting, and rugged eye-to-eye mounting, the Bilstein B8 8100 (DSA) is built to conquer demanding terrain while delivering a smooth, controlled, and confident ride. This is the ideal shock for drivers seeking the ultimate balance of comfort, capability, and adjustability in demanding off-road environments.
