S&S MR103C chain drive camshaft set- recommended for modified engines with larger displacement and higher compression. More torque and horsepower than bolt in cams can deliver. An S&S oil pump and cam support plate, along with a stock 2007 and later style hydraulic cam chain tensioner upgrade is highly recommended for chain drive cams. Performance intake and exhaust is recommended for maximum performance increase.
