Construction & Design

The BP-51 shock absorber is expertly crafted from aerospace-grade 6061 T6 aluminum, delivering a lightweight yet exceptionally strong structure. Every component, including the body and remote reservoir, undergoes a Type 3 hard anodizing process with a 40-micron coating. This treatment significantly improves resistance to corrosion, stone impacts, and abrasion commonly encountered during off-road use.

ARB’s in-house manufacturing ensures stringent quality standards are met, while the remote reservoir increases oil capacity and improves heat dissipation. This design prevents shock fade during extended or aggressive driving, maintaining consistent damping performance across a wide range of temperatures and terrains.
