3Racing 3RAC-PG6443 43T 64 Pitch Pinion - Hard Coated 7075  [3RAC-PG6443]

Precision 64 Pitch Pinion for Competitive Runs

The 3Racing 3RAC-PG6443 64 pitch 43T pinion is aimed at hobbyists who want reliable, repeatable gear engagement. Built from 7075 aluminium and finished with a hard coat, it offers wear resistance without adding excess mass. The 43-tooth configuration supports smooth torque transfer for both sprint runs and longer race formats.

Lightweight Strength for Frequent Running

7075 aluminium is chosen for its high strength to weight ratio, making this pinion suitable where durability and minimal rotational mass matter. The hard coating improves surface hardness to reduce tooth wear, making it a practical upgrade for regularly used cars and club racing gearboxes.

Engineered for Consistent Mesh and Driveability

With a 64 pitch specification and 43 teeth, this pinion is cut to deliver consistent meshing with matching spurs. That consistent engagement helps maintain smooth acceleration and predictable handling across a wide range of RC car models and setups.
