20T Mod1 Safe-D5 Pinion Gear (ARA310967)

20T Mod1 Safe-D5 Pinion Gear (ARA310967)

20-Tooth Mod1 Safe-D Pinion Gear is a tough steel pinion designed for RC models with a 5mm motor shaft. Its Safe-D design uses a D-shaped hole that matches the shaft profile, helping prevent the pinion from slipping if the set screw backs out, so drive power stays consistent and braking performance remains reliable.

Built for durability, it features a precise wide-tooth profile for smooth meshing with the spur gear and long-lasting performance in demanding RC conditions. The pinion is sized for a 5mm motor shaft and includes a precisely threaded hole for the set screw. The kit comes with a M4 x 4mm set screw and a 3.2mm E-clip to secure the pinion on the shaft.
