The RPM Traxxas X-Maxx Rear Bumper Mount is a beefy alternative to the small beam supports offered with stock parts. This upgrade is built more like a massive skid plate with tons of durability and flexibility to help absorb rear impacts and heavy rear-end-first collisions. Each RPM Rear Bumper Mount is designed from RPM's ultra-tough blend of engineering grade nylons for protection you can trust. Additionally, the Rear Bumper Mount comes with four small attachment points for the RPM Low Visibility Wheelie Bars (RPM81582 – sold separately)! If you’re tired of dragging or destroying your rear bumper, the combination of this Rear Bumper Mount and Low Visibility Wheelie Bars will solve those issues permanently!
