The Yokomo PG-6424A is a hard-coated aluminium pinion designed to balance durability and low mass for off-road and bashing rigs. Its 24-tooth layout at 64 pitch mates with like-spec spur gears to keep power delivery efficient.
The protective hard coat on the PG-6424A resists surface wear and preserves tooth profile when compared to untreated aluminium. That makes it a sensible upgrade for drivers who run often on abrasive surfaces.
Confirm your vehicle requires 64 pitch gearing before fitting the PG-6424A. Set a proper mesh, test rotation by hand, and recheck after a short break-in session to confirm even tooth contact.
