Tune your Mini-Z's transmission for silky smooth power delivery with this Machined Delrin Spur Gear. Designed by PN Racing, this gear is a critical component for high-end ball differentials.
Unlike standard molded plastic gears which can be slightly oval or warped, this gear is CNC Machined from Delrin. This ensures it is perfectly round and balanced, reducing vibration and noise in the drivetrain. The "B" in the part number indicates this version includes a high-precision Ball Bearing pre-installed or included for the center of the gear.
Key Features
-
64 Pitch (64P): Features ultra-fine teeth. Compared to standard Mini-Z gearing, 64 Pitch offers less rolling resistance, quieter operation, and significantly smoother acceleration. It also allows for much finer adjustments to your Gear Ratio.
-
Machined Delrin: The gold standard for RC gears. It is self-lubricating, incredibly durable, and lightweight.
-
Ball Bearing Center: Includes a high-quality ball bearing in the center bore.
This ensures the gear spins with zero wobble on the differential shaft, maintaining a perfect mesh with the pinion at all times. -
