Andrews 288131G 31G 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). Smooth idle, broad torque band. 2200-5800 RPm. 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 Gear drive uses less engine power to operate and improves valve timing accuracy over stock chain drive camshafts.
