ARRMA 29T 0.8Mod Safe-D5 RC Pinion Gear - ARA311012

The ARRMA ARA311012 is a 29T 0.8Mod Safe-D5 pinion gear designed as a direct-fit drivetrain component for compatible ARRMA electric RC vehicles. The Safe-D5 interface uses a flat-sided 5mm bore that locks securely onto the motor shaft without requiring a grub screw to bear directly on the shaft, helping to maintain a reliable, centred engagement between the pinion and spur gear. This RC pinion gear suits hobbyists replacing a worn part or selecting a specific tooth count to adjust their gear ratio.

Key Features

• 29-tooth, 0.8 module pitch pinion gear — mesh this with a compatible 0.8Mod spur gear for correct engagement
• Safe-D5 bore design uses a flat-sided 5mm shaft interface for a secure, centred fit without damaging the motor shaft
• Direct replacement for the factory pinion on supported ARRMA models listed by part number ARA4315V4, ARA4408V2, and ARA4410V2 variants
• Higher tooth count relative to a smaller pinion will raise top speed at the expense of low-end torque — confirm your intended ratio before fitting
• OEM ARRMA part supplied under style code ARA311012 for straightforward cross-referencing when ordering
