The line is built around two cam profiles. The 178\/208 is the milder grind, offered as a cast cam. The 188\/220 is the bigger grind, cut in steel. Both come as bare cams or as complete Camshaft Combos for 12-valve and 24-valve engines. For 2019-2024 6.7L Cummins trucks, their Flat Tappet Conversion swaps the factory roller lifter setup over to a flat tappet cam and lifters.

Hamilton Cams states the kit fits and is emission certified for all 2019-2024 Ram 2500 and 3500 diesels not in California. Hamilton does not do business in California, so the kit is not offered for California trucks. The lifter design it replaces is shared by the standard-output and high-output engines, and the kit is listed for both the 2500 and the 3500.\u003c\/p\u003e\n\u003cp\u003eIt is not listed for the 2025 and newer 6.7L. That engine has a redesigned block and head, and 2019-2024 engine parts should not be assumed to fit it. Our catalog tag reads 2019-current, but the kit's listed range is 2019-2024, so verify fitment by VIN. If your engine block or cylinder head has been surfaced, call before ordering so the kit can be verified for proper fitment.\u003c\/p\u003e\n\u003ch2\u003eWhy this part\u003c\/h2\u003e\n\u003cp\u003eThe hydraulic roller lifters in the 2019-2024 6.7L are the known weak spot of this engine. They have no needle bearings, run tight tolerances with undersized oil passages, and use a pressed steel alignment dowel that can back out. When a roller collapses or seizes, it gouges the camshaft and seeds the oil with metal. Watch for a typewriter-like tick on cold start that does not fade, metal in the oil, or a misfire. Some engines have shown it within the first 10,000 miles.\u003c\/p\u003e\n\u003cp\u003ePutting new factory-style lifters back in leaves you with the same design. This kit changes the design instead. Hamilton Cams calls the factory hydraulic roller lifters and camshaft problematic and converts the engine to a flat tappet setup: a forged cam, DLC-coated tappets, stiffer pushrods and adjustable rockers with DLC-coated trunnions. Valve lash is set at the adjustable rockers, and the kit is certified for street use in 49 states.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eHamilton Cams lists the kit contents as:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e178\/208 Forged camshaft\u003c\/li\u003e\n\u003cli\u003eDLC coated steel tappets\u003c\/li\u003e\n\u003cli\u003eUpgraded pushrods\u003c\/li\u003e\n\u003cli\u003eAdjustable rocker arms with DLC coated trunnions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eForged steel camshaft\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTighter Grain Structure: Hamilton's 178-208 steel cams are forged, not cut from bar stock, resulting in a more dense, more uniform grain structure.\u003c\/li\u003e\n\u003cli\u003eEnhanced Longevity: A natural “halo” in grain structure forms on the exterior of the cam during forging, adding a layer of strength for extended service life.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDLC-coated tappets\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGas Carburized \u0026amp; Polished: Each tappet goes through a hardening process that gives it the hardness to act as a very stable base metal for the DLC coating.\u003c\/li\u003e\n\u003cli\u003eDiamond-Like Carbon (DLC) Coating: A very hard surface finish that reduces friction and wear.

The factory oil for the stock 2019-2024 engine is 10W-30 or 5W-40 CK-4. With this kit in the engine, Hamilton Cams recommends:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eValvoline 15W-40 Premium Blue\u003c\/li\u003e\n\u003cli\u003eSchaeffer 700 Series 15W-40\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHere is why. Thin viscosity oils do not provide the hydrodynamic wedge a flat tappet needs, and oils low in zinc, phosphorus and molybdenum do not carry the additive package it needs. DLC lowers friction and extends part life, but incorrect oil, incorrect lash or valve float can damage it. High rpm amplifies the impact of the camshaft on the tappet, and Hamilton discourages high spring pressures and high rpm for longevity. When viscosity is too low, lash is too loose or rpm is too high, the oil film is not strong enough to keep the tappet and cam apart. The DLC then degrades into graphite and starts to decompose and delaminate.\u003c\/p\u003e\n\u003cp\u003ePlan this as cam-out engine work. On this engine, changing lifters in the frame means holding the lifters up with magnets while the cam is pulled and working through a trough in the cam tunnel. If a lifter drops, the oil pan has to come off. If you would rather not take that on, call the shop.\u003c\/p\u003e\n\u003ch2\u003eAbout Hamilton Cams\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/hamilton-cams\"\u003eHamilton Cams\u003c\/a\u003e builds valvetrain and top-end parts for the 5.9L and 6.7L Cummins out of Lampasas, Texas.

In engines over 500 horsepower, Hamilton says, high cylinder pressure starts to bend and buckle factory pushrods. When a pushrod deflects, you lose valve lift and the cam timing ends up retarded. Hamilton built these to solve that problem.\u003c\/p\u003e\n\u003cp\u003eThe numbers: a 12mm diameter with a .120″ wall, compared with the OEM 3\/8″ pushrod or a standard performance 7\/16″ pushrod. Hamilton rates buckling strength at up to 6,600 lbs against 1,780 lbs for OEM pushrods, and has tested them in builds exceeding 3,000 horsepower. Thicker walls and a larger diameter keep them stable under intense cylinder pressure, so valve lift stays consistent. Hamilton pitches them for everything from mild performance upgrades to full-blown race engines, and as the answer to OEM pushrod failures.\u003c\/p\u003e\n\u003cp\u003ePushrods are a standard part of the top-end package once power goes up. On 2003-2004 5.9L trucks, upgraded valve springs, pushrods, head studs and fire-ring gasket kits are the usual heads-and-studs path once boost and fueling are raised. On the 6.7L, the high-boost valvetrain list includes stiffer valve springs, upgraded pushrods, billet rocker-arm bridges and oversize valve seats.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHamilton Cams 07-p-004 24 Valve Extreme Duty Pushrods\u003c\/li\u003e\n\u003cli\u003e3-piece construction\u003c\/li\u003e\n\u003cli\u003e12mm diameter, .120″ wall thickness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngineered for Power\u003c\/strong\u003e: Tested in builds exceeding 3,000 horsepower, ensuring reliable performance at extreme power levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Strength\u003c\/strong\u003e: With a buckling strength of up to 6,600 lbs (compared to OEM pushrods at 1,780 lbs), you’ll get consistent valve lift and avoid retarded cam timing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision \u0026amp; Reliability\u003c\/strong\u003e: Thicker walls and a larger diameter provide improved stability under intense cylinder pressures, reducing the risk of deflection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDesign: 3-piece, 12mm diameter, .120″ wall thickness.
