Why You'll Love It

• Maximum Durability: Machined from high-quality steel and hardened to withstand extreme torque and heat.
• Precision Machining: Perfectly cut teeth ensure smooth meshing and efficient power transfer to your spur gear.
• Universal 5mm Fit: Designed specifically for high-power motors featuring a 5mm output shaft.
• 32 Pitch Strength: The larger tooth profile of 32P offers significantly more surface area and strength than smaller pitches.

What's Under the Hood

Robinson Racing has been the gold standard in RC gearing for decades. These pinions aren't your typical molded or soft-alloy gears; they are precision-machined from high-carbon steel and heat-treated to an "Extra Hard" specification. This process ensures the gear can handle the brutal snap of modern brushless ESCs without rounding off or shattering. The 5mm bore is standard for 1/8 scale motors and high-torque 1/10 scale brushless systems.
