It is made with a three-piece design to give the Slash owner the option of full front-end bash-proof and crash-proof protection with the skid plate mount, skid plate and bumper installed or if they're racing, they can remove the bumper and use the skid plate mount and skid plate as a light-weight alternative bumper / skid plate that sheds 27 grams (almost a full ounce) of weight from the front end of the truck. Once the race is over, simply reinstall the bumper and full bash protection is once again available.The Traxxas Slash 4x4 front bumper design eliminates the bumper support ring and the 4 screws behind the stock bumper while using a thicker skid design to supply the cushioning resistance a basher-proof bumper needs. By eliminating the stock bumper support ring, absolutely no frontal impact crash energy is transferred into the upper half of the differential housing. Supplied are longer bumper mounting screws as well, so any impact energy from down low has less of a tendency to pull the mounting screws out from the bottom half of the differential housing. With an RPM impact-absorbing front bumper installed, the energy transferred from frontal impacts will be greatly reduced as well.RPM light canister sets (RPM80982 & RPM80983) fully integrate with the Slash 4x4 front bumper and skid plate, giving the Slash 4x4 that awesome Desert Racing Truck look and open the 4x4 up to the addition of LED lights for nighttime fun! Don't forget to check out the Roof-Mounted Light Bar Set too (RPM80922, RPM80923 or RPM80925) for 6 more light canisters of night-blasting fun!
