Description

The 21T Mod1 Safe-D Pinion Gear is a rugged steel pinion designed for 5mm motor shafts in RC cars and trucks. Its Safe-D design features a D-shaped bore that matches the motor shaft to prevent drive loss if the set screw backs out, keeping the drivetrain engaged under load.

Includes a securing screw and E-clip for reliable retention, and a precision-made wide tooth profile for smooth meshing with the spur gear. Built to withstand extreme RC conditions, this 21-tooth pinion delivers durable, long-lasting performance on the track or in rugged terrain while fitting 5mm motor shafts.
