High-strength 25T pinion 1st gear made from tough 7075 T6 alu, large and specially hardcoated for superior strength, high durability and long life. The large size allows the engine to be further away from the bulkheads to ensure all standard engines fit perfectly.
Created on a special gear machine, all pinions feature ultra-precise tooth shaping and ultra-true running for vibration-free operation. Fine internal threading allows easy installation on XCA clutchbells (standard or lightweight versions). Each pinion is fine etched with the tooth number for quick & easy identification.
Available in popular gearing sizes, allowing you to find the perfect gear ratio for any track.
