Built for Long Life: 48 Pitch 21T Pinion

This 21-tooth 48 pitch pinion is aimed at RC hobbyists who want a durable drivetrain upgrade. Machined from 7075 aluminum with a hard coated finish, the 3RAC-PG4821 resists abrasion while preserving precise tooth geometry.

Performance and Compatibility

Engineered to provide smooth power transfer, this pinion works well with a wide range of 1/10 scale vehicles that use 48 pitch gearing. It offers stable mesh and consistent engagement for both on-road and off-road rigs.

Why Choose 7075 Aluminum?

7075 is prized for its high strength-to-weight ratio, giving you a robust gear that does not add unnecessary mass. The hard coating further reduces surface wear, extending service life under heavy use.

Installation Tips

When fitting the 3RAC-PG4821, check pinion-to-spur alignment and set gear mesh carefully to avoid premature wear. Periodic inspection and proper lubrication will help maintain peak performance.

Will this pinion fit most 1/10 cars that use 48 pitch gears?

The pinion suits the majority of 1/10 scale models running 48 pitch setups, but always verify your spur gear tooth count and shaft size before installation.

What maintenance keeps the pinion working longer?

Regular cleaning to remove grit, checking mesh, and light lubrication on the bearings and gear surfaces will preserve the hard coating and extend service life.
