Engineered specifically for Cummins applications, these tappets feature a maximized crown designed to promote proper tappet rotation and provide a more consistent contact surface between the tappet and camshaft.\u003c\/p\u003e\n\n\u003cp\u003eColt Cams developed these tappets after identifying inconsistencies in the crown profiles of many tappets currently available on the market. Some aftermarket tappets can have crowns that are too flat or even dished, which can negatively affect the rotation required for proper valvetrain operation. Colt addressed this issue by using measurements similar to standard Cummins tappets while maximizing the crown.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Tappet Crown Matters\u003c\/h3\u003e\n\n\u003cp\u003eThe tappet's crown plays an important role in maintaining proper rotation as it contacts the camshaft. Colt Cams designed these tappets with a \u003cstrong\u003emaximum crown profile\u003c\/strong\u003e to help ensure consistent rotation during engine operation. This is particularly important when installing a performance camshaft where proper tappet-to-cam contact is critical.\u003c\/p\u003e\n\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003e5.9L\/6.7L Cummins\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThese tappets are designed for Cummins applications and are an excellent complement to Colt Cams performance camshafts. Verify engine and camshaft compatibility before installation.\u003c\/p\u003e\n\n\u003ch3\u003eBreak-In Procedure\u003c\/h3\u003e\n\n\u003cp\u003eWhen used with a flat-tappet camshaft, proper break-in is critical. Apply cam lube to all cam lobes and tappet faces, and oil the appropriate bearing journals and lifter barrels before assembly. Always turn the engine over by hand before starting it to verify clearances and proper timing location.\u003c\/p\u003e\n\n\u003cp\u003eColt Cams recommends starting the engine and running it at approximately \u003cstrong\u003e1,800–2,000 RPM for 18–20 minutes\u003c\/strong\u003e. Because modern engine oils may contain reduced levels of anti-scuff additives, Colt Cams also recommends using an appropriate zinc-based additive during flat-tappet camshaft break-in.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Always verify proper tappet, camshaft, and engine compatibility before installation. Follow the camshaft manufacturer's recommended break-in procedure when installing new tappets with a new camshaft.\u003c\/p\u003e","brand":"Colt Cams","offers":[{"title":"Default Title","offer_id":53861736153453,"sku":"CC-CCTAPPETS","price":136.0,"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-89-26-dodge-ram-5-9l-6-7l-cummins","provider":"Diesel Power Products","version":"1.0","type":"link"}
