From the Manufacturer When Traxxas first announced the 4x4 version of the Slash RPM customers immediately started asking us if our 2wd version parts would fit it. Sadly that was not the case. Since then we?ve been working hard to make all of those RPM parts 2wd owners love fit on the Slash 4x4 version. Our three-piece front bumper / skid plate design for the Traxxas 4x4 is simple yet strong effective and highly attractive. We made it 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! Our 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. We supply 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 front bumpers for the Traxxas Slash 4x4 are available in three color options: black on black blue on blue or a chrome bumper on a gray skid plate. We?re so confident in the strength and durability of these new bumpers that they too come with our unbeatable factory warranty protection.
