King Off-road Racing Shocks are some of the finest and highest performing shocks in the entire world. The same components that go into their legendary trophy trucks also go into every OEM performance kit, ready for immediate bolt on installation. The superior 3" shock bodies with additional finned reservoirs provide dramatically improved heat disippation and damping abilities through the toughest terrains on earth. The fins act as a heatsink for the reservoirs, accelerating heat exchange from the shock fluid, to optimize internal shock temperatures and operating pressures. Every kit has been optimally tuned with precise damping curves and spring rates to provide the ultimate performance for your specific vehicle.
