Precision Pinion Upgrade for Drivetrains

The Yokomo PG-4831A Precision Hard Coated Aluminum Pinion Gear gives RC hobbyists a dependable 31-tooth option for 48-pitch setups. Its tooth profile is matched to standard 48-pitch spur gears to help maintain smooth power delivery through the drivetrain.

Benefits of the 31T Hard-Coated Aluminium Pinion

Constructed from hard-coated aluminum, this pinion balances low mass with improved surface wear resistance, making it suitable for spirited track runs or weekend club racing. Accurate machining reduces backlash and helps protect mating gears over time.

Model Fitment and Typical Uses

Made for models that use 48-pitch gearing, the pinion is ideal for tuners adjusting gear ratios to favour either higher top speed or stronger acceleration depending on spur selection. It is a straightforward upgrade for both competitive and hobby-grade vehicles.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this pinion mesh with any 48-pitch spur gear?

Yes, the gear is manufactured to 48-pitch specifications so it will mesh with compatible spur gears when installed with correct mesh and shimming.

Do I need special tools to fit the Yokomo PG-4831A?

Installation typically requires standard hex drivers and a pinion spanner for trimming or holding. Ensure the set screw is tightened securely and check mesh after a short run.

How does hard-coated aluminium compare to steel pinions?

Hard-coated aluminium offers weight savings and good surface durability for most hobby use, while steel can be heavier and more resistant to extreme wear at the cost of extra mass.
