ARP ARP6410A Pro Series 10-tooth angled pinion gear for serious slot-car drivetrains.

This precision 64-pitch, 5° angled pinion is machined from heat-treated stainless steel and sized for a 2mm (0.078") motor shaft. The angled tooth form is intended for compatible angled gear setups where proper mesh can reduce friction and improve durability compared with forcing a straight-cut pinion into the wrong geometry.

Why racers use it

• 10 teeth / 64 pitch: common high-performance gearing format for commercial and competition slot cars.
• 5° tooth angle: designed to mesh correctly with compatible angled axle gears.
• Heat-treated stainless steel: ARP specifies hardness of approximately RC 36–38 for durability.
• 2mm bore: fits common 2mm motor shafts.
• Solder-on installation: gives a positive connection when installed correctly.
• Protective shoulder: helps keep solder away from the gear teeth during installation.

Pro setup note: Match pitch and tooth angle to the axle gear before installation. Use only enough solder to secure the pinion, keep heat and solder away from the teeth, and verify free gear mesh before running the motor under load.
