64P 31T Pinion Gear Aluminum Pro (RRP4331)

64P 31-tooth Aluminum Pro Pinion Gear is a precision-machined, lightweight pinion for RC car drivetrains. Made from aircraft-grade aluminum, it is lightened to reduce rotating mass and double-coated with a hard black anodize for durability. Although typically recommended for on-road use, it can also be run off-road.

This pinion features a 1/8-inch bore and includes a 5-40 set screw. A 1/16-inch hex wrench is required to secure the screw, but is not included. The tooth count is stamped on the gear for quick identification, and the combination of aluminum construction, lightening, and the hard anodized finish supports smooth engagement and long-lasting wear resistance.
