PTK8652 48P Lightweight Hard Anodized Aluminum Pinion Gear (5.0mm Bore) (32T)

This pinion gear is a lightweight, precision-machined aluminum upgrade from ProTek RC designed for 48-pitch (48P) drivetrains in competitive RC drag racing and other high-power electric applications. The 32-tooth count and 5 mm bore suit motors with larger shaft diameters often found on 4-pole drag racing motors, delivering engagement with matching 48P spur gears. Machined aluminum and a hard anodized finish reduce rotating mass compared with heavier steel gears, which can help improve throttle response and quicker motor spool-up. Etched tooth size markings offer easy identification during setup and gearing changes.
