The Harley-Davidson Evolution engine, commonly known as the Evo, was introduced in 1984 as a revolutionary update to the brand's V-Twin engines. The Evo engine, which powered Harley-Davidson motorcycles through the 1990s, featured significant improvements in reliability, performance, and durability over the previous Shovelhead engine. Central to the Evo's design were its cams, which played a vital role in enhancing valve timing and overall engine efficiency. The Evo cams contributed to the engine's smooth power delivery, improved cooling, and reduced mechanical noise, making it a beloved choice among riders. The Evolution engine and its cams are celebrated for reviving Harley-Davidson's reputation for producing durable, high-performing motorcycles, and they remain highly regarded in the Harley-Davidson community to this day.
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.
