ARRMA 12T Mod1 Safe-D5 RC Pinion Gear - ARA311052

The ARRMA ARA311052 is a 12T Mod1 Safe-D5 pinion gear designed as a direct-fit spare for a range of ARRMA brushless RC cars. This RC pinion gear uses the Safe-D5 bore system, which provides a secure, concentric fit on 5mm motor shafts without the need for grub screws biting directly into the shaft — reducing shaft damage during installation and removal. The 12-tooth, Mod1 tooth profile is suited to the high-torque drivetrains found across ARRMA's 1/7 and 1/8 scale platforms.

Key Features

• 12-tooth Mod1 pinion gear for use with Mod1 spur gears across compatible ARRMA models
• Safe-D5 bore design clamps securely to 5mm motor shafts while protecting the shaft surface
• Direct replacement part using ARRMA style code ARA311052 for straightforward identification
• Suitable for the high-power brushless motor setups used in ARRMA's larger 1/7 and 1/8 scale vehicles
• Retaining the stock 12T tooth count keeps your gearing ratio unchanged from factory specification
