The BP-51 is a user-adjustable internal bypass 4WD shock absorber that provides increased comfort and control, both on and off-road.
All BP-51 shock absorbers are designed and manufactured in-house by ARB using state-of-the-art machining and hard-anodizing equipment.
The body of a BP-51 shock is constructed from 6061 anodized aluminum to dissipate heat more efficiently than steel or alloy steel and provide superior corrosion resistance.
Extensive dynamometer, real-world and destructive testing has been undertaken throughout the development process to ensure reliability, longevity and performance meet ARB’s impeccable standards.
Unlike other adjustable shock absorbers, which only provide adjustment for compression, the BP-51’s flexibility allows for independent adjustment of rebound and compression. This unique feature enables personalized driving customization, allowing adjustments to suit the specific requirements of each trip or excursion, making the BP-51 a market leader in its category. The new range of high-performance BP-51 bypass shock absorbers is the result of an exhaustive development process aimed at delivering the ultimate in comfort and control. Designed, developed, and thoroughly tested by ARB’s Ride Control Engineering team, the BP-51 shock absorbers are specifically tailored for each vehicle and utilize pre-existing mounting points for easy installation without the need for additional modifications to the vehicle.
