Description

The ARRMA Pinion Gear - 38T Mod1 Safe-D8 (ARA311126) is a tough steel pinion engineered for smooth, reliable power delivery in demanding RC conditions. A wide Mod 1 tooth profile and precise machining help reduce noise and wear, while the D-shaped bore matches 8mm motor shafts to maintain drive and braking even if the set screw loosens. An included E-clip provides added pinion retention on suitable motors.

  • Precision manufactured wide tooth profile for smooth operation
  • 'D' shaped hole to match motor shaft profile so drive and brakes are not lost if the set-screw backs-out

  • Precision manufactured threaded set-screw hole
  • E-clip supplied for motor shaft pinion retention
