S&S Cycle 585G Gear Drive Camshaft Kit for Twin Cam Engines - Part #33-5268
The S&S Cycle 585G Gear Drive Camshaft Kit (Part #33-5268) is designed for use with 88, 96, 103, and 110 cubic-inch Twin Cam engines, offering improved performance and reliability. This kit features camshafts and gear components tailored to enhance engine operation by reversing the rear cam's rotation, which increases operating clearance between cam lobes and facilitates higher cam lift capabilities. Such modifications contribute to improved valve timing accuracy by eliminating chain lash and reducing issues associated with loosely fitting stock chain drives. Installation requires removing material from the inner surface of the stock gear cover, and a hydraulic press along with professional tools are necessary for proper setup. For optimal results, S&S recommends using adjustable pushrod covers and replacing cam bearings and gaskets during installation. The kit includes camshafts, inner and outer gears, bearings, gaskets, and detailed instructions to ensure a comprehensive upgrade. It is essential to check valve-to-valve and valve-to-piston clearance, as well as coil bind, prior to operation. Due to the gear drive design, increased valve train noise may be experienced. This American-made product provides a durable and high-performance solution for serious motorcycle enthusiasts seeking to maximize engine output and efficiency.
