Performance-proven by the Slash 4X4 Ultimate and 1/10 Rally, the Traxxas Low-CG chassis is now available as a complete conversion kit for Slash 4X4. No matter where you want to race, on the track or off, you will experience superior handling and faster corner speed. The conversion kit includes all the parts and hardware required to convert one Slash 4X4 to the Low-CG configuration. The Low-CG chassis holds the battery* and electronics* as deep in the chassis as possible to position weight low in the chassis. To prevent flex under load, the chassis is reinforced by integrated ribs that form a ridged triangulated structure. Underneath, the chassis is ultra-smooth to reduce drag and prevent snags whether you're blasting through whoops on the track or blazing trails in your backyard. The low-CG design dramatically increases corner speed and stability no matter where you drive. If your Slash 4X4 is destined for the track, the Low-CG chassis is ready to accept your personal transponder. Bosses integrated into the chassis make it easy to mount the transponder with two screws, no tape required. And of course, the transponder mounts up front, so it gets to the finish line faster!
