The TRX4015T is a 15T pinion gear engineered for TRAXXAS TRX4 Trail Crawler applications and supplied as a 2 pcs set for replacement or gearing swaps. Pinions are produced to a 32 pitch with 0.8mm tooth spacing to ensure accurate meshing with standard TRX4-compatible spur gears used in serious scale crawling setups.
Manufactured from hardened steel #45 for enhanced wear resistance, the component features a true 3.175mm centre bore to match common motor shafts and a 15-tooth profile for low-speed, high-torque operation. The delivery also contains one 3x3 screw shaft (1 pc) to secure the pinion to the motor where applicable.
Technical notes for installers and tuners: verify motor shaft diameter and spur pitch before assembly, set correct backlash and mesh to prolong gear life, and select the 15T profile to prioritise torque for technical crawling lines rather than top speed. This part is designed for RC scale use and precision upgrade performance.
