Those tuning their drivetrains will find this hard-coated aluminium pinion a solid option for reliable gearing. The PG-6437A is built to a 64-pitch standard with 37 teeth to mesh cleanly with compatible spur gears.
Using aluminium helps cut rotating mass, which can improve acceleration and reduce strain on the motor. The hard-coating boosts surface toughness so the pinion holds up better under repeated running.
With its 64DP specification, this pinion fits many RC cars that use the same pitch spur gears. It is a practical choice for routine maintenance, gearing swaps and modest performance upgrades across varied terrain.
