Construction & Design

ARB’s BP51 shock absorbers are precision-engineered using premium materials to withstand the rigors of off-road driving. The shock body and remote reservoir are machined from 6061 T6 aluminum, a lightweight yet high-strength alloy known for excellent heat dissipation. This helps maintain consistent damping performance even under extreme conditions. The Type 3 hard anodized finish provides a durable protective layer that resists corrosion, stone chips, and debris damage commonly encountered on trails.

The internal valving is designed for position-sensitive damping, allowing the shock to adapt dynamically throughout the suspension travel. This technology delivers a smooth, controlled ride during normal driving and firm, responsive damping when the suspension reaches its limits off-road. ARB’s in-house manufacturing process ensures tight tolerances and consistent quality across every unit, reflecting their commitment to reliability and performance.

Installation & Fitment

The ARB BP51 Long Front Shock Absorber is engineered for straightforward installation on Jeep Wrangler JL models from 2018 to 2023 fitted with 2.5 to 3.5-inch lift kits. It fits Sport, Sport S, Rubicon, Sahara, Willys, and special edition trims such as the 80th Anniversary and Freedom editions. No vehicle modifications are necessary, as the shock absorber bolts directly onto the factory mounting points, preserving factory alignment and suspension geometry.

This direct bolt-on design ensures a hassle-free upgrade process, allowing Jeep owners to quickly enhance their suspension performance without the need for additional parts or complex adjustments.
