Fastrax 48DP 13T 7075 Aluminium Pinion Gear

The Fastrax 48DP 13T Aluminium 7075 Pinion Gear (FAST48-13) is a precision-machined 48 pitch pinion designed to deliver smooth, consistent gear mesh in RC drivetrain setups. Crafted from high-grade 7075 aluminium, it helps minimise rotating mass while maintaining durability for efficient power transfer.

Overview

With a 13-tooth count, this pinion offers a lower gear ratio choice that can aid acceleration and control when paired with a matching 48DP spur gear. The 48DP tooth profile is widely used for fine, accurate meshing, supporting reliable driveline performance when set up correctly.

To get the best from this pinion, select the tooth count to suit your preferred balance of top speed and torque, and set a precise gear mesh with adequate backlash. Periodically inspect the teeth and replace if wear is evident to maintain smooth operation.
