3RACING 21T 64 Pitch Pinion 7075 Hard Coated - 3RAC-PG6421  [3RAC-PG6421]

High precision 3Racing pinion for tuned performance

The 3Racing 64 Pitch Pinion Gear 21T is a compact, hard wearing upgrade for RC drivetrains. Constructed from 7075 aluminium with a hard coat, it retains strength while keeping weight down for crisper throttle response.

Where this 21T pinion helps

With a 64 pitch tooth profile, this pinion promotes smooth power delivery and clean meshing, useful in high speed runs or tightly tuned gearing where consistency lap to lap is important.

Simple installation pointers

Align the pinion carefully with the spur and verify the set screw torque to stop slippage. Proper mesh reduces noise and extends both pinion and spur life during regular club or clubnight use.
