Traxxas Ring Gear & Pinion 12/47 Ratio Front RC Differential - 6778

The Traxxas TRX6778 is a front differential ring and pinion gear set featuring a 12/47 tooth ratio, designed as a direct-fit internal replacement for Traxxas models that use this differential specification. If you're rebuilding or servicing a worn front differential, this gear set restores the drivetrain to factory specification without requiring a full differential assembly replacement. The 12/47 ratio is a Traxxas factory spec, so fitment and performance characteristics remain consistent with the original build.
