Track tuned 48 pitch pinion

The 3RACING 48 Pitch Pinion Gear 33T suits modelers who want reliable gearing on the track or at the park. Built from 7075 aluminum, it balances lightness and strength for predictable drivetrain behaviour.

Hard coated surface for longer life

A protective hard coating improves resistance to tooth wear and scuffing under load. The precision tooth shape helps maintain smooth power transfer and reduces gear noise during acceleration.

Versatile for many 1/10 scale vehicles

This 33T pinion works well across a range of 1/10 scale platforms, from touring cars to buggy builds. Installation is straightforward, letting you experiment with different ratios to suit your driving style.

Does 3RACING 3RAC-PG4833 require shimming adjustments?

You should check pinion to spur mesh and adjust shims if needed for optimal contact. Proper mesh reduces wear and improves efficiency.

Is the 7075 alloy prone to stripping?

7075 offers a good strength to weight ratio. With correct mesh and the hard coating, the risk of stripped teeth is minimised compared to softer alloys.

Will this change my gear ratio significantly?

Changing pinion tooth count alters ratio directly. Moving to a 33T will shift top speed and acceleration depending on your spur size, so plan swaps accordingly.

Any tips for installation?

Align the motor and gearbox securely, set the gear mesh with a feeler or paper method, and tighten the pinion grub screw while preventing the motor from rotating.
