BK series

K-MAN Baja shocks was specially developed for Baja racing. Based on many years of experience in developing and manufacturing suspension for international race events, the new Baja shocks designed to meet the demands of long-distance and high-intensity working conditions. The complete set consists of BK-4.5 shocks, BK-3.0 shocks and BK-2.5 bump. BK-4.5 designed in PDD (Progressive Displacement Damping System) structure with built-in multi-channel. Double-cylinder structure, oil and nitrogen separated design, through different sizes and positions holes to adjust the oil flow, damping forces can be controlled by both speed and displacement. Also equipped with high and low speed compression and rebound adjuster. BK-3.0 shocks equipped with double piston control system, with adjustments of high speed and low speed compression, rebound adjustment and inside compression and rebound hydraulic bump function. BK-2.5 bump, the rear bump adopted DPS (Double Piston Control System), mono tube structure, with floating piston to separate oil and nitrogen, dual-piston control system to achieve the control of inflection force.
