Castle Creations 32-pitch (Mod 0.8) pinion gears are precision-machined from green anodized aluminum and feature an oversized Allen set screw for a secure fit. These pinions are commonly used with 1/8-scale monster trucks such as the Traxxas E-Maxx and E-Revo.
They are available in tooth counts of 16T, 18T, 20T, 22T, 24T, 26T, and 28T.
Each pinion has a 5 mm bore and comes with a 4 mm set screw; installation requires a 1.5 mm hex wrench to fasten it to the motor shaft.
