The Traxxas 7789 rebuild kit for slipper clutch is a replacement parts kit that refreshes the slipper clutch components in compatible Traxxas RC vehicles. It includes a steel disc, friction insert, spring, 2.5×12 mm pin, and a 4 mm nylon locknut to restore proper clutch engagement, improve drivetrain performance, and maintain traction control during acceleration. This kit is primarily designed for use with the Traxxas X-Maxx series of monster trucks and fits the stock slipper clutch setup found on those models, helping extend the life of worn parts and keep your vehicle running smoothly. Be sure to check your owner’s manual or parts list to confirm that part number 7789 is correct for your specific Traxxas chassis before ordering.
