From forged steel camshafts to DLC-coated tappets and robust pushrods, every component is engineered for maximum performance and reliability. Trust in our decades of research, thousands of dyno tests, and millions of real-world miles to deliver a kit that stands the test of time.\u003c\/p\u003e\n\u003cp\u003eWhen you choose Hamilton Cams, you're investing in proven innovation and superior craftsmanship. Experience the confidence that comes from a kit designed to hold up under extreme conditions, and help your Cummins engine deliver reliable power for the long haul.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures and Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTighter Grain Structure: Our 178 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\u003cli\u003eGas Carburized \u0026amp; Polished: Each tappet undergoes a meticulous hardening process that creates a stable, hardened base metal for the DLC coating.\u003c\/li\u003e\n\u003cli\u003eDiamond-Like Carbon (DLC) Coating: This ultra-hard surface dramatically reduces friction and wear, but proper operating conditions are critical for long service life. DLC can be damaged by incorrect oil, improper valve lash, valve float, excessive RPM, excessive spring pressure, or metal contamination. Always use a quality 15W-40 oil (or 5W-40 in sub-zero temperatures) containing adequate zinc, phosphorus, and molybdenum. Low-viscosity or low-additive oils do not provide the film strength required for flat tappet operation.\u003c\/li\u003e\n\u003cli\u003e3500+ lbs Buckling Force: Compared to around 1800 lbs for OEM pushrods, ours drastically reduce deflection at high cylinder pressures.\u003c\/li\u003e\n\u003cli\u003eConsistent Valve Timing: With less flex, your valvetrain stays precisely in sync - even under extreme conditions.\u003c\/li\u003e\n\u003cli\u003eHigh-Quality Casting: Built to handle intense stress and heat cycles.\u003c\/li\u003e\n\u003cli\u003eGas Carburized Ball \u0026amp; Foot: Reduces friction and wear for longer service intervals.\u003c\/li\u003e\n\u003cli\u003eDLC-Coated Trunnion: Minimizes galling - an all-too-common issue with OEM trunnions - and lowers overall friction in the valvetrain.\u003c\/li\u003e\n\u003cli\u003eDecades of Experience: Our cams have powered countless diesel engines for millions of road miles and thousands of dyno runs.\u003c\/li\u003e\n\u003cli\u003eSEMA-Certified (49-State Compliance): This kit is tested and certified for street use in 49 states, giving you peace of mind.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSold As: Kit\u003c\/li\u003e\n\u003cli\u003eUniversal: No\u003c\/li\u003e\n\u003cli\u003eVehicle Type: Truck\u003c\/li\u003e\n\u003cli\u003eLiter: 6.7L\u003c\/li\u003e\n\u003cli\u003eFuel Type: Diesel\u003c\/li\u003e\n\u003cli\u003eValve: 24-Valve\u003c\/li\u003e\n\u003cli\u003eInjection System: Common Rail\u003c\/li\u003e\n\u003cli\u003eCoating: DLC (Tappets and Rocker Arm Trunnions)\u003c\/li\u003e\n\u003cli\u003eRPM Range: Below 4,000 RPM with OEM Valve Springs\u003c\/li\u003e\n\u003cli\u003eValve Lash: .010 Inch Intake \/ .020 Inch Exhaust\u003c\/li\u003e\n\u003cli\u003eBuckling Strength: 3,500+ lb (Pushrods)\u003c\/li\u003e\n\u003cli\u003eKit Contents: Forged Steel Camshaft, DLC-Coated Tappets, Heavy-Duty Pushrods, Upgraded Rocker Arms\u003c\/li\u003e\n\u003cli\u003eEmissions Compliance: SEMA Certified 49-State Street Use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFitment Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFitment: 2025-2026 Ram 6.7L Cummins 24-Valve engines being converted to a Hamilton Cams flat-tappet system; rocker-arm core charge applies.\u003c\/li\u003e\n\u003cli\u003eIf you've had your engine block or cylinder head surfaced, please call us for verification to ensure proper kit fitment.\u003c\/li\u003e\n\u003cli\u003eIntake Valve Lash: 0.010 Inch\u003c\/li\u003e\n\u003cli\u003eExhaust Valve Lash: 0.020 Inch\u003c\/li\u003e\n\u003cli\u003eWe will require a core charge on rocker arms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWe require Valvoline Premium Blue or Schaeffer's 15W-40 (5W-40 in sub-zero conditions).
