This is an RPM Rear Bumper in Pink for the Traxxas Electric Rustler. RPM's Rustler rear bumper is designed to protect the rear of the chassis, the motor, and the body, all while still allowing the use of a stock Traxxas Wheelie Bar (TRA3678, not included). Additionally, if you decide to run without the Wheelie Bar, the rear bumper will adapt and allow either configuration. The RPM Rear Bumper for the electric Rustler is designed tough, with serious impact absorption characteristics built in. With the use of an RPM Rear Bumper Mount (RPM80902 or RPM80905 not included), the protection for the motor becomes nearly indestructible! Each RPM Rear Bumper is made in the USA from engineering grade nylons and is backed by a limited lifetime warranty against breakage.
