Buggy Champ Ball Diff Set II, RC option part

The Buggy Champ Ball Diff Set II brings a classic drivetrain upgrade back into the regular Hop-Up Option parts series and gives compatible buggy re-issues a more efficient, more controllable way to deliver power. Built around a ball differential mechanism, the set supports finer tuning than a fixed differential feel and suits running sessions where traction changes across dirt, gravel, or mixed surfaces. This re-issue follows the previously limited edition release 84113 and makes the same upgrade available again as a standard option part. The included hardware covers key internal components for the assembly, with a 1150 ball bearing, 8 differential balls in 3 mm size, and 4 mm and 5 mm screws listed in the set contents. Differential adjustment can be carried out while the unit remains installed in the gearbox, which simplifies service access during routine tuning and lets setup changes happen with less disassembly. Compatibility is stated for Item 58441 Buggy Champ 2009, Item 58452 Sand Scorcher 2010, and Item 47304 Fighting Buggy 2014. For restoration projects, period-style buggy builds, or regular track use, this option part adds a concrete tuning step to the drivetrain rather than a cosmetic change. It fits naturally into workshop sessions focused on traction balance, throttle response, and maintaining classic rear-drive buggy platforms with period-correct upgrade parts.
