S&S Cycle Camshaft Kit 583G Gear Drive for Twin Cam Engines - Part #330-0107

The S&S Cycle Camshaft Kit 583G (Part #330-0107) is designed for Twin Cam engines, offering a significant upgrade in performance and valve train reliability. This gear drive system reverses the rotation of the rear cam, providing extra operating clearance between cam lobes, which enables higher cam lifts and improved airflow. By eliminating timing chain lash and loosely fitting stock chains, this kit enhances valve timing accuracy, resulting in more precise engine operation and increased power output. The kit delivers strong low-end torque and horsepower, with optimal performance typically observed between 1,500 and 5,000 RPM, making it suitable for riders seeking increased acceleration and engine responsiveness. Installation requires removing material from the inner surface of the stock gear cover and the use of a hydraulic press along with professional tools. The kit includes camshafts, inner gears, outer drive gears, bearings, gaskets, and detailed instructions, ensuring a comprehensive upgrade. Made in the USA, this upgrade is ideal for experienced technicians or enthusiasts familiar with gear drive systems. Due to the inherent characteristics of gear drives, increased valve train noise may be noticeable. Proper installation mandates checking for coil bind, valve-to-valve, and valve-to-piston clearances. It is not recommended for engines with compression ratios exceeding 10.1:1, ensuring optimal performance and durability under specified conditions.
