Precision Pinion for Tough RC Action 3RACING 3RAC-PG6425

The 3RACING 64 Pitch Pinion Gear 25T is built to give consistent tooth engagement in demanding running. Crafted from 7075 aluminum and finished with a protective hard coating, it delivers a good balance of weight savings and surface resistance.

Features Overview for the Pinion

Material: 7075 aluminum offers strong mechanical properties while keeping mass low.
Durability: Hard coating reduces surface wear to help the pinion last through multiple sessions.
Compatibility: Intended for vehicles that take a 64 pitch, 25-tooth pinion.

Suitability and Strength

This pinion suits drivers who swap gearing for track or rough terrain and need a reliable tooth profile. Proper mesh setup will maximise life and performance.

Will this pinion change top speed?

To alter top speed you change tooth count relative to your spur gear; this 25T pinion will affect ratio depending on the spur you pair it with.

Is 7075 aluminum better than other alloys?

7075 is commonly used for its high strength; combined with the hard coating it offers improved wear life versus softer alloys.

Do I need a new pinion for a brushless motor?

Not necessarily; match pitch and tooth count, and ensure the motor spline and shaft diameter match the pinion bore for secure mounting.

How to check correct mesh?

Set a minimal backlash and run a thin coat of grease to spot tight or loose contact, then fine tune motor position until engagement is even across the tooth face.
