S&S Cycle 106-4868 Camshaft Kit for Twin Cam and Dyna Engines with 96-106 CID Displacement

The S&S Cycle 106-4868 camshaft kit is designed for engines with a displacement of 96 to 106 cubic inches and a compression ratio between 9:1 and 9.9:1. This bolt-in cam set is ideal for stock or mildly modified touring bikes, offering a straightforward upgrade to enhance engine performance. The kit features a gear drive system that reverses the rear cam's rotation direction, providing increased operating clearance between cam lobes and allowing for higher cam lift potential. This results in improved power output across the entire rpm range, with the strongest gains observed from 1,000 to 4,000 rpm, especially in low and midrange torque. The gear drive system also increases valve timing accuracy by eliminating timing chain lash and compensates for loosely fitting stock chains, ensuring smoother operation and more precise timing. Installation requires removing material from the inner surface of the stock gear cover and utilizing professional tools such as a hydraulic press. The kit includes inner and outer gears, bearings, gaskets, and comprehensive instructions. For optimal performance and durability, S&S recommends using an adjustable pushrod and cover kit during installation. Please note that this camshaft kit is not recommended for engines with compression ratios of 10:1 or higher and may produce increased valve train noise due to gear drive characteristics. Proper inspection of coil bind, valve-to-valve clearance, and valve-to-piston clearance is essential before installation. Made in the USA, this camshaft kit is a reliable upgrade for enthusiasts seeking increased power and improved engine response in their Twin Cam or Dyna models.
