Extra Hard Steel 32P Pinion Gear 18T 5mm Bore - RRP8618

Bulletproof your drivetrain with the legendary durability of Robinson Racing steel.

When you are pushing high-voltage brushless power through your RC rig, the pinion gear is often the first point of failure. Robinson Racing’s Extra Hard Steel series is engineered to eliminate that weak link. This 18-tooth pinion is specifically designed for 32-pitch spur gears and fits motors with a 5mm output shaft, making it a go-to choice for heavy-duty 1/10 scale builds and 1/8 scale bashers.

Robinson Racing has been the industry standard for precision gearing for decades. These gears aren't just cut; they are machined from high-quality steel and hardened to withstand the brutal torque of modern hobby-grade electronics. Whether you are aiming for a new speed record or tackling a technical rock crawl, this pinion delivers the consistent mesh and long-term reliability you need.

Why You'll Love It

• Hardened Steel Construction: Designed to outlast aluminum and standard steel gears under extreme loads.
• Precision Machined Teeth: Ensures a smooth, quiet mesh that reduces friction and maximizes power transfer.
• 5mm Bore: Perfect fit for most high-performance 36mm and 40mm brushless motors.
• Industry Leading Durability: Robinson Racing’s signature heat-treatment process provides maximum wear resistance.

What's Under the Hood

This pinion features a wide face to maximize contact area with the spur gear, reducing the risk of stripped teeth during hard acceleration or braking. The included 4mm set screw provides a secure hold on the motor shaft, ensuring your gear stays exactly where you set it even in high-vibration environments.
