Andrews 12G Gear Drive Camshafts - 288112G

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)
Similar timing to earlier stock 88 cams but gear drive cams are used instead of chain
No engine retuning necessary with this timing
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
