The S&S Cycle Camshaft Kit 585G is designed specifically for Twin Cam engines with 88 to 110 cubic inches, providing enhanced performance and reliability. This gear drive kit features a reverse rotation camshaft that improves operating clearance between cam lobes, accommodating higher lift cams and optimizing valve timing. The kit includes all necessary components such as camshafts, inner and outer gears, bearings, gaskets, and detailed installation instructions, making it suitable for professional installation.
The gear drive system effectively eliminates chain lash and loose fit issues common with stock chain drives, resulting in increased valve timing accuracy and smoother engine operation. To ensure proper installation, the inner surface of the stock gear cover must be machined, and a hydraulic press along with other professional tools are required. S&S recommends using adjustable pushrod covers during installation and replacing cam bearings and gaskets for best results.
This kit is built to operate efficiently at engine speeds ranging from 2,500 to 6,000 RPM, depending on engine size. Due to the gear drive design, users might experience increased valve train noise, which is a typical characteristic of gear-driven systems. The S&S Cycle Camshaft Kit 585G is proudly made in the USA and is engineered for riders seeking increased durability and performance from their Twin Cam engine. Proper clearance checks such as coil bind, valve-to-valve, and valve-to-piston should be performed during installation to ensure optimal operation and longevity of the engine components.
