Sturdy 48 Pitch 21T Pinion from 3RACING

The 3RACING 3RAC-PG4821 48 Pitch 21T pinion is precision made from 7075 aluminum and finished with a hard coat to reduce wear and extend gear life during aggressive driving.

Smooth Power Delivery and Fit

This pinion is engineered to deliver consistent power transfer with minimal noise, fitting a wide range of 1/10 scale models that use a 48 pitch gearset for straightforward integration into common setups.

7075 Aluminum Advantages

7075 aluminum offers an excellent strength to weight ratio, keeping rotating mass low while resisting deformation. The hard coating boosts abrasion resistance so the gear holds up under repeated use.

Fitting and Maintenance Tips

Align the pinion carefully with the spur gear and check mesh and set screw tightness after initial runs. Periodic inspection and light lubrication of the mesh area will help prevent premature wear.

If your buggy uses a 48 pitch pinion and the motor shaft matches the pinion bore or can be adapted, the 3RACING 3RAC-PG4821 should fit. Confirm shaft diameter and spacing before installing.
Set a slight backlash by positioning the pinion so there is minimal play between teeth, then tighten the motor clamp and recheck mesh after a short run to ensure nothing has shifted.
The hard coat prolongs life even for occasional drivers by improving abrasion resistance, though heavy racers will see the biggest benefit from the tougher finish.
