Pinion Gear Overview:

Arrma Safe-D5 Mod1 Pinion Gears feature a "D" shaped hole that allows the motor shaft to key inside the pinion gear, eliminating the loss of drive and brakes if the set screws comes loose. This tough steel Pinion Gear is available in multiple tooth count options, allowing you to fine tune the gear ratio. Use the pull down menu above to pick the pinion gear for your application.


  • Strong and durable steel for long-lasting performance in extreme RC conditions
  • 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
  • Suits 5mm motor shaft diameter
  • Precision manufactured threaded set-screw hole
  • E-clip supplied for motor shaft pinion retention


  • (1) Mod1 Safe-D Pinion Gear
  • (1) Set Screw (4x4mm)
  • (1) E-Clip (3.2mm)

Safe-D pinions are the only pinions I run. They last a long time, and you don’t have them fly off and get lost if they happen to come loose. Best pinion on the market.

Will not fit the kraton 8s, Arrma and affiliates really need to update their specs. The newer kraton have a 8mm bore not 5mm.
