Hamilton Cams Cummins Tappets are solid valve lifters and are available for Cummins 24-valve and 12-valve 6-cylinder engines. They are also offered for Cummins 4BT 4-cylinder (8-valve) engines.
Cast tappets for 6-cylinder engines feature a 1.450 in. diameter and do not interfere with the fuel pump eccentric on 12-valve engines. Much wider than the 1.100 in. tappets used in early 12-valve engines, their greater surface area makes them perfect replacements. These 24-valve and 12-valve tappets work well with the wider lobes of Hamilton Cams camshafts and promote much better lobe life with today's low zinc oils.
For use over 5,000 rpm, with heavy valve springs, or a billet steel cam, Hamilton Cams offers 1.450 in. steel tappets. They are specially designed and manufactured to handle the higher pressures, rpm, and loads of competition use.
Hamilton Cams Cummins 4BT tappets have a 1.300 in. diameter; much wider than many 4BT tappets that are only 1.10 in. These cast 1.300 in. tappets allow the pressures between the camshaft and the tappet to be spread over a significantly larger surface area to reduce lobe and lifter wear.
