{"product_id":"lifters-tappets","title":"Lifters\/Tappets","description":"\u003cp\u003eHamilton 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.\u003c\/p\u003e\n\u003cp\u003eCast 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.\u003c\/p\u003e\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\u003cp\u003eHamilton 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.\u003c\/p\u003e","brand":"Hamilton Cams","offers":[{"title":"Default Title","offer_id":42868595327111,"sku":"07-t-4bt","price":149.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/4855\/4631\/files\/hml-07-t-4bt_89d2af56-92fd-4e19-bea0-cc1284210a8c.jpg?v=1778524284","url":"https:\/\/fullsenddiesel.com\/products\/lifters-tappets","provider":"Full Send Diesel","version":"1.0","type":"link"}
