Features

• Andrews Products grinds its cams with the help of a computer with cam design capabilities. This superior technology gives the utmost in both performance and reliability. Only the best alloy steel billets and heat-treating processes are utilized. Furthermore, the power in Harley’s Evolution engines can be made even more convincing when a superior Andrews computer-designed highperformance cam is installed. These hydraulic lifter cams are capable of 6000-plus rpm with stock springs and no valve float. Made in the U.S.A.
• Bolt-in cam for light bikes (FXRS, etc.) adds significant mid-range power without affecting idle
• A 6000+ rpm cam for stock heads and springs with hydraulic lifters
• Designed for mildly stroked motors or motors with head work done
