ProTek RC 48P Hard Anodized Aluminum Pinion Gear 31T - PTK-8618

Drop rotating mass and dial in your final drive ratio with this precision-cut 31-tooth pinion.

The ProTek RC 48P Lightweight Hard Anodized Aluminum Pinion Gear is engineered for racers and drivers aiming to trim rotational inertia without sacrificing longevity. Built for standard 1/10 scale 540 and 550 electric motors sporting a 3.17mm (1/8 inch) output shaft, this 31T pinion ensures a smooth, quiet, and efficient mesh against standard 48-pitch spur gears.

Why You'll Love It

• Hard Anodized Finish: Surface-hardened aluminum resists tooth wear and handles abrasive track grit better than untreated alloys.
• Lightened Construction: Relieved material cuts rotating drivetrain weight, helping improve motor efficiency and instantaneous throttle snap.
• Precision 3.17mm Bore: Machined to close tolerances for a true, wobble-free fit on standard 1/8 inch motor shafts.
• Laser-Etched Markings: Clear tooth count etching allows quick gear identification right out of your pit organizer.
