ARRMA 15T 0.8mod 4x4 RC Pinion Gear - ARAC7875

The ARRMA ARAC7875 is a 15-tooth, 0.8 module pinion gear designed as a direct-fit drivetrain component for ARRMA 4x4 platform vehicles. Pinion gears are a critical part of the RC drivetrain, connecting the motor to the spur gear and directly influencing the gear ratio, so having the correct tooth count and module size is essential for reliable performance. The AR310424 reference makes it straightforward to cross-check compatibility when ordering a replacement for your ARRMA 4x4 model.
