Howards Cams Max Certified Camshafts are camshaft and lifter kits that are backed by a five-year no-fault warranty from Howards Cams. Each of these kits utilizes an excellent hydraulic camshaft with matching flat tappet lifters to provide excellent power boosts. Most of these camshaft and lifters kits are available with optional Direct Lube lifters to increase oil flow to the camshaft (part numbers that end in "D"). Included in each kit is a bottle of Max ZPM oil additive designed to greatly aid in camshaft break-in. The five-year no-fault warranty will cover your camshaft and lifters if they are damaged for any reason, even if it gets dropped and breaks in two!
