PTK8648 48P Lightweight Hard Anodized Aluminum Pinion Gear (5.0mm Bore) (28T)

This is a lightweight, hard anodized aluminum 48-pitch pinion gear from ProTek RC with a 5.0 mm bore and 28-tooth count. Designed for high-performance RC applications such as drag racing and other electric builds that use 48P gear systems, it mounts to larger motor shafts often found in 4-pole motors for efficient power delivery. The machined aluminum construction reduces rotating mass compared with steel gears, promoting quicker motor spool-up and improved throttle response. Precision-cut teeth ensure smooth engagement with matching spur gears for consistent operation and reliable mesh.

• 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
