In typical RPM fashion, we don't just make replacement parts, we make the best replacement parts possible. So what sets the RPM rear bumper above all else? We started with our incredibly durable materials and created a bumper that is based off of current full-sized Short Course and Baja style rear bumpers. Full-sized rear bumpers are wide and flat and our scale version is exactly that, for the ultimate in rear-end protection. RPM rear bumpers will stop most rear impacts from affecting the truck in any negative way. Additionally, RPM rear bumpers for the Traxxas Slash weigh in at a full 9 grams (18%) lighter than the stock version. Lighter is always faster. What more could we do to make these things incredibly realistic? How about mounting points for mud flaps? That's right, these bumpers come stock with mounting positions for RPM Mud Flaps (#81012 - available separately). Now the Slash owner can run mud flaps for ultra-realistic good looks. RPM rear bumpers for the Traxxas Slash are available in three popular color options – black, blue and chrome. RPM rear bumpers are sold with all necessary mounting hardware and complete mounting instructions.
