RCD offers the largest selection of quality Blower Pulleys/Blower Sprockets available, from any manufacture. We manufacture and stock standard Blower Pulley sizes and tooth profiles in 5mm, 8mm, 11mm, 13.9mm and 14mm and the only manufacture that offers a complete Blower Pulley line available with various offsets, non-standard tooth sizes and is able to produce custom sizes or special materials upon request. Our Blower Pulleys are profiled to produce a stronger sprocket for the rigorous demands of drag racing. Blower Pulley teeth are cut on state-of-the-art gear shaping equipment using the exact tooth profile tooling from Gates, ensuring a proper mesh of the Blower Belt to the Blower Sprocket, thus providing better wear and less drag on the drive system.
