Whether you’re kitting out your 4WD straight from the showroom, or it’s just become time, upgrading your vehicle’s suspension is something you’re going to enjoy every time you get behind the wheel!
ARB’s latest product developed under the Old Man Emu brand is the revolutionary BP-51 shock absorber. BP-51 is the next generation of 4×4 suspension; combining leading technology used to control high-performance off road race vehicles with an everyday four-wheel-drive application.
Unlike any other adjustable shock absorber, which provide adjustment for compression only, the BP-51 range allows on-vehicle, independent adjustability of both rebound and compression to offer class leading ride customisation that can be tailored to the individual vehicle or trip requirements.
Each shock absorber is individually designed to suit a specific make and model of 4×4 with no vehicle modifications; engineered and tested to ensure a perfect match to your vehicle.
BP-51, there’s nothing quite like it.
In addition to the velocity sensitive damping used in most shock absorbers, where the faster the piston moves, the higher the level of damping is generated, BP-51 shock absorbers also generate damping dependent on the position of the piston within the shock absorber’s body via their bypass design.
While most shock absorbers only generate damping based on fluid flowing through the piston, the BP-51 offers an alternative path from one chamber to the other, around the piston in the form of bypass passages. Some fluid flows through the piston and some fluid bypasses around the piston in the bypass passages.
This results in an ability for the shock absorber to provide the best of both worlds, with a comfortable and compliant ride during normal driving and a more controlled ride over more challenging terrain. With greater levels of damping generated at each end of the stroke, the piston slows as it approaches full compression and extension, preventing harsh topping out against the bump stop and allowing larger bumps and corrugations to be absorbed more easily.

All BP-51 shock absorbers are manufactured in-house by ARB. In order to achieve this, significant investment has been made in state of the art machining and hard anodising equipment, allowing ARB total control of the process to ensure the highest possible quality.
BP-51 shock absorber bodies are manufactured using aircraft grade (6061) anodised aluminium to dissipate heat more efficiently than steel or alloy steel and provide superior corrosion resistance.
Extensive lab, real world and destructive testing has been undertaken during the development process to ensure that reliability, longevity and performance all meet ARB’s impeccable standards.Read the Y62 Patrol Development Story
