After 4 years in development, ARB recently released its new suspension system: the Old Man Emu (OME) BP–51 high performance shock absorbers.

Bringing racing technology to everyday applications, BP-51 (bypass 51mm diameter bore) shock absorbers feature “revolutionary, patent-pending technology developed to deliver unparalleled on and off road performance”.

Developed and tested extensively in some of Australia’s most rugged environments, these bigwith remote reservoir, are designed to be fitted without any need for vehicle modification.

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. The shock absorber has been designed to deliver a comfortable ride during normal driving and a more controlled ride over 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.

Furthermore, damping performance isadjustable across a wide range in both rebound and compression, allowing the user to alter the vehicle’s ride performance to cater for different road conditions and vehicle loading scenarios. The body, reservoir and components are all made from aircraft grade (6061 T6) aluminium, with a type 3, 40 micron hard-anodised finish, ensuring exceptional heat dissipation and resistance to corrosion and stone damage.

Other features include: vehicle specific applications; adjustable spring preload/ride height adjustment; high pressure nitrogen reservoir with aluminium, anodised floating piston; 19mm hard chromed ground shaft with impact resistant, replaceable shaft guard; dash 6 high temperature Teflon® hose with high flow fittings; and large Teflon® lined spherical bearings on coil over applications.
