Series HG gear drive cams are made for ALL (’07 - up) Twin cam engines and ’06 DynaGlides. They have been designed to run with new 2007 S&S gear drives. The cam lobe designs listed below are the same as those manufactured for 1999-2006 engines. Gear drives made for ’99-2006 engines will not fit (2007 - up) Twin cam engines or 2006 Dyna engines. HG cam installation kits include two plates for blocking lubricating oil feed holes which were intended for stock chain drives, not 2007 style gear drives. Performance gains with the HG cams listed will be similar to ’99-’06 engines running with the same cam grinds.
Big cams for modified 96 - 120+ inch motors running 10:2 CR or higher. Heads must be set for .700 lift and modified for max air flow. (3000-6500+ RPM).
