Andrews 288159G 59G Gear Drive Camshafts

Gear drive uses less engine power to operate and improves valve timing accuracy over stock chain drive camshafts. Dynamometer comparisons show gains of 4 horsepower over chain drive camshafts. Can be installed on both carbureted and fuel injected models (exc. 2006 Dyna). Great cam for 95in. motors with 10.00 CR and higher. Max torque and HP at mid and upper RPm. NOTE: Requires spring spacing. NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. NOTE: Sold as cams only, inner and outer gear kit and installation kit must be purchased separately. NOTE: 59G cams are for highly tuned engines and require the knowledge of an expert engine builder for proper setup and installation.
