ProTek RC 48P Aluminum Pinion Gear 30T 3.17mm - PTK-8617

Drop rotational mass and fine-tune your final drive ratio with an ultra-lightweight, hard-anodized aluminum pinion.

The ProTek RC 48 Pitch 30T Pinion Gear is machined from high-grade aluminum and treated with a hard-anodized coating to withstand high-RPM running in both stock and modified racing classes. Sized specifically for standard 3.17mm (1/8 inch) motor shafts, it trims critical rotating mass from your driveline to help sharpen throttle response and keep motor temps down.

Why You'll Love It

• Lightweight Aluminum Construction: Lowers rotating weight across the drivetrain for punchier acceleration out of corners.
• Hard-Anodized Surface: Extends gear tooth lifespan and resists wear against composite or nylon spur gears.
• Laser-Etched Markings: High-contrast tooth count etched directly on the barrel saves you from squinting and counting teeth in the pits.
• Precise 3.17mm Bore: Slides smoothly onto standard 540-size motor shafts with tight tolerances to prevent wobble and runout.
