2005-2023 Toyota Tacoma BP-51 Front Coilover

Bring race technology to your adventures!

Old Man Emu's BP-51 Suspension system, featuring revolutionary patent-pending technology developed to deliver unparalleled on and off road performance. For use on coil over models, BP-51 employs high-quality X5K grade steel coils that incorporate application-specific design. Because they are engineered, developed, tested and manufactured entirely in-house by the Old Man Emu team, ARB can guarantee the highest possible quality.

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.

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