These heavy-duty tappets feature a \u003cstrong\u003e1.30-inch diameter\u003c\/strong\u003e, compared to the 1.10-inch diameter found on many 4BT tappets, helping spread the pressure between the camshaft and tappet across a larger contact area.\u003c\/p\u003e\n\n\u003cp\u003eThe increased contact area makes these tappets an excellent choice for 4BT engines equipped with performance camshafts. They are an ideal complement to the \u003cstrong\u003eColt Cams Stage 3 Camshaft for 4BT Cummins\u003c\/strong\u003e and are designed to provide a robust foundation for a performance-oriented valvetrain.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Use Larger 4BT Tappets?\u003c\/h3\u003e\n\n\u003cp\u003ePerformance camshafts can place increased demands on the valvetrain. Colt Cams designed these 4BT tappets with a \u003cstrong\u003e1.30-inch diameter\u003c\/strong\u003e to provide a larger contact surface between the cam and tappet. Compared with many 1.10-inch 4BT tappets, the larger diameter helps spread the pressure over a wider area, making these tappets well suited to performance-oriented engine builds.\u003c\/p\u003e\n\n\u003ch3\u003eIdeal for 4BT Performance Builds\u003c\/h3\u003e\n\n\u003cp\u003eThese tappets are a natural match for a performance 4BT valvetrain. When paired with a Colt Cams performance camshaft and appropriate pushrods, they provide an upgraded foundation for engines being built for increased performance, towing, competition, or demanding industrial applications.\u003c\/p\u003e\n\n\u003ch3\u003eBreak-In Procedure\u003c\/h3\u003e\n\n\u003cp\u003eWhen installing new tappets with a flat-tappet camshaft, proper break-in is critical. Apply cam lube to all cam lobes and tappet faces, and oil the bearing journals and tappet barrels before assembly.\u003c\/p\u003e\n\n\u003cp\u003eBefore starting the engine, always turn it over by hand to verify proper clearances and cam timing. Colt Cams recommends starting the engine and running it at approximately \u003cstrong\u003e1,800–2,000 RPM for 18–20 minutes\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eBecause modern engine oils may contain reduced levels of anti-scuff additives, Colt Cams recommends using an appropriate \u003cstrong\u003ezinc-based additive\u003c\/strong\u003e during initial flat-tappet camshaft break-in.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Always verify tappet, camshaft, pushrod, and engine compatibility before installation. Follow the camshaft manufacturer's recommended break-in procedure when installing new tappets.\u003c\/p\u003e","brand":"Colt Cams","offers":[{"title":"Default Title","offer_id":53861772886381,"sku":"CC-CCTAPPETS-4BT","price":109.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2487\/2301\/files\/COLTCAMS_COLTCAMS_1_86747573-2edd-4808-ba4c-7d4ce4294efd.jpg?v=1788391869","url":"https:\/\/dieselpowerproducts.com\/products\/colt-cams-tappets-dodge-ram-4bt-cummins","provider":"Diesel Power Products","version":"1.0","type":"link"}
