Traxxas 15-T Pinion 48 Pitch 2.3mm Shaft RC Gear - 7039

The Traxxas 7039 is a 15-tooth pinion gear designed for 48-pitch drivetrains using a 2.3mm motor shaft, supplied with a set screw for secure fitment. Pinion gears are a common wear item and a straightforward swap when you need to restore drivetrain performance or adjust your gear ratio. The TRX7039 is a genuine Traxxas part, machined to the correct pitch and bore to drop straight into compatible Traxxas models without modification.

Key Features

• 15-tooth (15T) pinion gear cut to 48-pitch, compatible with standard 48-pitch spur gears
• Designed for a 2.3mm motor shaft, suiting many Traxxas brushed and brushless motor setups
• Includes a set screw to lock the pinion firmly onto the motor shaft and prevent slipping
• Genuine Traxxas spare part, ensuring consistent mesh and correct tolerances for compatible models
• Changing pinion tooth count alters your top speed and acceleration balance — a lower tooth count increases torque, a higher count increases top speed
