The Arrma ARA311011 28T 0.8Mod Safe-D5 Pinion Gear is a tough steel upgrade designed for smooth, reliable power delivery in demanding RC conditions.

The Safe-D5 design uses a D-shaped bore to match a 5mm motor shaft, helping maintain drive and braking even if the set-screw backs out. A threaded set-screw hole and supplied E-clip add extra security on the motor shaft.
