Precision Engineered Pinion for 48 Pitch Setups

The Yokomo PG-4839A Precision Hard Coated Aluminum Pinion Gear provides a lightweight, accurately cut option for 48 pitch drivetrains. Its 39T configuration helps deliver consistent engagement for track and club use.

Model Compatibility Overview

Designed to pair with standard 48 pitch spur gears, the PG-4839A suits a wide range of 1/10 on-road vehicles. Use it when refining gear ratios for lap consistency or tighter acceleration control.

Longevity from Hard Coated Aluminium

The hard-coated aluminium construction balances low mass with improved surface hardness to resist wear. Precision tooth profiles aid cleaner meshing, extending service life and reducing maintenance frequency.
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 work with steel spurs?

Yes, it is compatible with steel or alloy 48 pitch spurs. Ensure correct mesh to avoid premature wear on either component.

What are the signs the pinion needs replacing?

Look for rounding of teeth, tooth chipping, or increased backlash. Any unusual vibration or noise under load also signals inspection is needed.

Is there a break-in procedure?

Run the car gently for a short period after installation to seat the teeth, then recheck mesh and retighten set screws as necessary.

Can I polish the pinion after wear starts?

Light surface cleaning is fine, but avoid material removal that changes tooth profile. If teeth show significant wear, replacement is recommended rather than polishing.

Does the tooth count affect gearing options?

Yes, the 39T tooth count alters final drive ratio compared with other sizes. Choose counts to balance top speed and acceleration for your setup.
