XRAY's narrow pinion gears, crafted with precision and unparalleled concentricity, offer true leading-edge design and production. Post-machining, the pinions undergo a special treatment for an even hard-coating, ensuring their long-lasting reliability. They are compatible with most spur gears, and when paired with XRAY spur gears, they significantly reduce throttle on/off noise. Made from lightweight aircraft duraluminum, these pinions are 1.5mm thinner and 25% lighter than regular pinion gears.
