    Old Man Emu brings racing technology to every day adventures: BP-51 (Bypass 51mm diameter bore) shock absorbers feature revolutionary, patent pending technology developed to deliver unparalleled on and off road performance. Developed and extensively tested under the harshest conditions in Australia, these big bore, position sensitive bypass shock absorbers with remote reservoir are designed to bolt onto your vehicle without any vehicle modifications and combine considerable ride comfort around town with significant amounts of end-zone damping for exceptional chassis control and handling off road. The damping performance is easily adjustable across a wide range of rebound and compression, resulting in significant changes to the ride performance of your vehicle, enabling a custom tune to suit the conditions and vehicle set up. The body, reservoir and components are all made from 6061 T6 aluminum, Type 3 40 micron hard anodized ensuring exceptional heat dissipation, corrosion resistance and resistance to stone damage. Not only designed, developed and tested entirely by ARB's team of Old Man Emu ride engineers, 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 machinery providing ARB total control of the manufacturing process to ensure the highest possible quality. ;

    Product Highlights

    • suspension_bp-51-bore

      POSITION SENSITIVE DAMPING

      Damping increases as you get closer to the end zone, meaning you’ll experience increased control at end zones and comfort at ride height.

    • suspension_bp-51-adjustable

      ADJUSTABLE

      External, independent rebound and compression on-car adjustment allows fine tuning of ride comfort and control to suit varying vehicle, load and trip requirements.

    • suspension_bp-51-ports

      QUALITY ALUMINIUM MATERIAL

      51mm bore, 6061 grade aluminium shock absorber body with type III, hard anodised finish for increased heat dissipation and corrosion resistance.

    • suspension_bp-51-material

      BOLT-IN APPLICATION SPECIFIC

      Every BP-51 is expertly engineered to bolt-in to your vehicle, meaning no fitting modifications are required and no adjustments.

    BP-51 (BYPASS 51MM DIAMETER BORE) SHOCK ABSORBERS

    The new BP-51 range of high performance, bypass shock absorbers is the result of an exhaustive development process aimed at delivering the ultimate in both comfort and control. Designed, developed and tested entirely in-house by ARB’s team of Old Man Emu ride engineers, BP-51 shock absorbers are vehicle-specific and utilize existing mounting locations to provide easy installation without the need for additional vehicle modification. Unlike most other adjustable shock absorbers, 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 customization that can be tailored to an individual vehicle or trip requirements.

    BYPASS TECHNOLOGY

    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.

    DEVELOPMENT AND MANUFACTURING

    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) anodized aluminum to dissipate heat more efficiently than steel or alloy steel and provide superior corrosion resistance. Extensive lab, real world and destructive testing have been undertaken during the development process to ensure that reliability, longevity and performance all meet ARB’s impeccable standards.
