PTK8649 48P Lightweight Hard Anodized Aluminum Pinion Gear (5.0mm Bore) (29T)

This pinion gear is a lightweight, hard anodized aluminum upgrade from ProTek RC designed for 48-pitch (48P) RC drivetrains that use a 5.0 mm bore motor shaft. The 29-tooth count offers a balance between acceleration and top speed in electric builds such as drag cars, buggies, and trucks. Machined aluminum construction reduces rotating mass compared with heavier steel gears, helping the motor spool up quicker under throttle. Precision cut 48P teeth ensure smooth mesh engagement with matching spur gears for efficient power transfer in performance-oriented setups.

• 48 Pitch with a 5mm pinion bore for larger 4-pole drag motors
• Machined from aluminum and given a hard anodized for durability
• Etched tooth size for easy identification
