Construction & Design

The BP51 shock absorber is crafted from premium materials and engineered for durability and performance. Its body and remote reservoir are constructed from 6061 T6 aluminum, prized for its strength-to-weight ratio and excellent thermal conductivity. The Type 3 hard anodized finish provides a 40-micron thick protective layer that guards against corrosion, abrasion, and stone impacts, ensuring long-lasting resilience in rugged environments.

ARB’s in-house manufacturing process guarantees that every component meets exacting standards. The position-sensitive bypass design allows the shock to modulate damping forces dynamically, balancing comfort and control by adapting to varying terrain and driving conditions. This engineering results in a shock absorber that performs consistently and reliably over time.
