ARP 6410A Pro Series 10-tooth, 64-pitch, 5° angled stainless-steel pinion gear with 2mm bore.

This is a precision solder-on pinion for serious slot-car drivetrains. ARP machines the gear from heat-treated stainless steel and adds a shoulder at the base of the teeth to help keep solder out of the gear mesh during installation.

Why racers use it

• 10-tooth / 64-pitch: a common high-performance combination for fine-pitch slot-car gearing.
• 5° angled tooth form: designed for compatible angled axle gears and useful in carefully set up inline applications where the angle can help reduce drag.
• Heat-treated stainless steel: strong, wear-resistant and suitable for repeated race use.
• 2mm bore: sized for standard 2mm motor shafts.
• Solder-on fit: gives a secure installation for high-RPM use when fitted correctly.
• Protective shoulder: helps prevent solder from flowing into the gear teeth.

Racer's setup note: Match pitch and angle to the axle gear, confirm proper mesh before soldering, and use only enough solder to secure the pinion. Keep heat and solder away from the tooth form. A smooth mesh should turn freely with minimal backlash and no tight spots.
