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 (excluding bar ends) 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. Complete (3 Piece) Kits are a convenient all-in-one package and include matching Shogun Frame, Bar End, and Swingarm Sliders (Spools). 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.
