ARRMA 16T 0.8Mod Safe-D5 RC Pinion Gear - ARA310999

The ARRMA ARA310999 is a 16-tooth, 0.8 module pinion gear with a Safe-D5 bore, designed as a direct-fit drivetrain component for a wide range of ARRMA electric RC cars. The Safe-D5 interface uses a flat-sided bore that grips the motor shaft securely without needing a grub screw to bite into the shaft directly, helping to protect both the gear and the motor over time. If you're replacing a worn pinion or restoring a stripped drivetrain, this is the correct OEM-spec part for the compatible ARRMA models listed below.

Key Features

• 16-tooth, 0.8 module specification suits the standard gear pitch used across multiple ARRMA electric platforms
• Safe-D5 bore design provides a secure fit on the motor shaft without relying solely on a set screw biting into bare metal
• Direct OEM replacement — matches the original factory spec so no modification is needed during installation
• Compatible across a broad spread of ARRMA Typhon, Kraton, Talion, Notorious, and Infraction models
