Shogun sliders are superior to other slider brands by virtue of their construction and material. Shogun pucks, bar ends and spools are made of shatter-proof UHMW infused with UV-protective polymer. Each slider has a press-fit aluminum bushing to hold it in place during impact to reduce the risk of the slider puck or spool tearing off of the mounting point. Shogun sliders absorb kinetic energy from crashes and will not fade in the sun nor shatter in cold temperature like some types of Delrin. Frame sliders are the most cost effective way to provide vital protection to your frame, motor, engine cases, and in some instances, bodywork, in the event of a crash. Each frame slider is manufactured from a proprietary blend of composite materials to maximize the absorption of kinetic energy and minimize friction.
