Medium Load Suspension Lift Kit with BP-51 Bypass Shocks

ARB 4X4 Accessories is proud to announce BP-51 Suspension Kits for 5th Generation Toyota 4Runner applications. Bring race technology to your adventures with OME's BP-51 suspension kit, featuring revolutionary patent-pending technology developed to deliver unparalleled on and off road performance. These bolt-on, big bore, position sensitive internal bypass shock absorbers have been developed and tested to provide exceptional ride comfort around town with significant amounts of end-zone damping for exceptional chassis control and handling off road. BP-51 shock absorbers provide greater levels of damping at each end of the stroke based on position and velocity of the piston. This provides a comfortable and compliant ride during normal driving, improved control over challenging terrain and prevents harsh topping/bottoming out through bumpy roads. Damping performance is easily adjustable across a wide range in both rebound and compression, allowing the driver to customize the vehicle's ride performance for road conditions, vehicle load scenarios and personal preference. The body, reservoir and components are all made from aircraft grade (6061 T6) aluminum, with a type 3, 40 micron hard anodized finish, ensuring exceptional heat dissipation and resistance to corrosion and stone damage. Designed, developed, tested and manufactured entirely in-house by ARB's team of Old Man Emu Engineers to guarantee the highest possible quality, all BP-51 shock absorbers come with a 3-year warranty.

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.
