Maximum Drivetrain PowerEngineered for high performance setups
Upgrade your RC car drivetrain with the Extra Hard 21 Tooth Blackened Steel 32p Pinion, 5mm. Designed for extreme durability, this high-performance gear pairs perfectly with brushless motor power systems in heavy-duty off-road and street applications. Heat-treated high carbon steel construction ensures smooth power delivery and reduced gear wear under heavy load.
Unmatched Strength & PrecisionBuilt to withstand intense brushless torque
When running high-power brushless setups in Traxxas, Associated, or HPI scale models, standard brass or aluminum pinions can strip under high torque. The Extra Hard 21 Tooth Blackened Steel 32p Pinion, 5mm utilizes heat-treated high carbon steel with superior natural lubricity, making it an ideal match for metal spur gears and GEN3 slipper units. Each pinion gear is precision machined and clearly stamped with the tooth count for quick identification in your toolbox. Complete with a 4mm set screw, this 32 pitch gear (.8 module compatible) delivers the ultimate mesh strength required for aggressive bashing and competitive RC racing.
