AR310476 Steel Pinion Gear 15T Mod1 5mm (ARAC7776)

This 15-tooth MOD1 steel pinion gear is designed as a direct replacement for the factory pinion on 5mm motor shafts.

Made from tough steel for long-lasting performance in extreme RC conditions, it features a precise tooth profile for smooth, reliable meshing. Two set-screw holes let screws bite from either side of a 5mm motor shaft for a secure, slip-free fit. The package includes one steel 15T MOD1 pinion gear and two M4x4mm set screws, compatible with 5mm shafts.
