The Harley-Davidson Twin Cam engine, introduced in 1999, marked a major advancement in the evolution of the brand's iconic V-Twin engines. The Twin Cam, named for its two camshafts, offered improved performance, reliability, and durability compared to its predecessors, such as the Evolution engine. With increased displacement and enhanced cooling, the Twin Cam provided a significant boost in power and torque, making it a favorite among riders seeking strong, consistent performance. The design of the Twin Cam engine focused on reducing mechanical noise and improving overall efficiency, ensuring that Harley-Davidson motorcycles maintained their reputation for delivering a powerful and smooth riding experience.
Wood Performance cams are designed and tested with authentic Harley Davidson lifter guides.
The use of third-party lifter guides may impact your results or damage your engine.
