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.
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.Some fluid flows through the piston and some fluid bypasses around the piston in the bypass passages. 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. In order to achieve this, significant investment has been made in state High-quality X5K grade steel coil, for use on coil over models, incorporates application-specific design;Large, Teflon-lined spherical bearings;6061 grade aluminum spring seat, top hat, spring preload/ride height adjuster;Durable Dash 6 high-temperature Teflon hose incorporates high-flow fittings for optimum oil flow;6061 grade aluminum remote oil canister allows for increased oil volume, resulting in lower oil temperatures;Sold individually;Image is representative, actual product may differ;California Residents: WARNING ARB Old Man Emu BP51 Coilover Shock - BP5190005L 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.
