Old Man Emu brings racing technology to everyday 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 setup. 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, but all BP-51 shock absorbers are also manufactured in-house by ARB. 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. ;
