The Traxxas 7789 rebuild kit for slipper clutch is a replacement parts kit designed to refresh the slipper clutch assembly in certain Traxxas RC vehicles that use the steel-disc style slipper system. It includes a steel disc, a friction insert, a spring, a 2.5×12 mm dowel pin, and a 4 mm nylon locknut to help restore smooth clutch engagement, consistent drivetrain performance, and reliable traction control under acceleration. This rebuild kit is primarily intended for the Traxxas X-Maxx monster truck platform, especially the original 6S X-Maxx models that use that style of slipper clutch. Make sure to check your vehicle’s exploded parts diagram to confirm that part 7789 matches your specific model and slipper clutch setup before purchasing.
