heavy duty alloy and carbon fiber mounting base that secures the extra wide high density, high impact foam bumper. Inside the foam bumper are three alloy posts for extra secure foam bumper mounting.
The design also allows you to experiment with adding nylon body posts (Traxxas TRA4214, etc not included) onto the bumper or perhaps a lexan body lip (splitter) on the under side of the bumper (body posts or splitter not included). This set is designed to work with most street eliminator bodies.
