Precision 48 Pitch 39T Pinion from 3Racing 3RAC-PG4839

For hobbyists focused on consistent track performance, the 3Racing 3RAC-PG4839 48 pitch 39T pinion is machined from 7075 aluminum to balance strength and low weight. The hard coating increases surface durability so the gear keeps running smoothly through repeated sessions.

Design Highlights and Typical Uses

This pinion suits a broad range of 48 pitch drivetrains and lets you fine tune speed versus torque thanks to its 39 teeth profile. The hard coat lowers friction at the mesh and helps resist wear, supporting cleaner power transfer and longer service intervals.
