While DLC is a big leap forward to lower friction and extend part life, it can be damaged by using incorrect oil, incorrect lash, or experiencing valve float. Thin viscosity oils, do not provide the correct hydro-dynamic wedge flat tappets need. Oils with low  zinc, phosphorous and molybdenum do not provide the additive package needed for a flat tappet.  Lash that is too loose can damage lifters or coating by increasing the impact when lash goes to solid. Make sure your lash is correct. High rpm amplifies the impact of the camshaft to the tappet. High spring pressures and high rpm are discouraged for longevity’s sake.  In these scenarios where viscosity is too low, lash is too much or rpm too high, the film strength is not adequate to keep the tappet and the cam separated. In this case the DLC will be degraded into graphite and will start to decompose and delaminate.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p1\"\u003eHeavy-Duty Pushrods\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\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 class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eConsistent Valve Timing: With less flex, your valvetrain stays precisely in sync—even under extreme conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p1\"\u003eUpgraded Rocker Arms\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eHigh-Quality Casting: Built to handle intense stress and heat cycles.\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eGas Carburized Ball \u0026amp; Foot: Reduces friction and wear for longer service intervals.\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eDLC-Coated Trunnion: Minimizes galling—an all-too-common issue with OEM trunnions—and lowers overall friction in the valvetrain.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p1\"\u003eProven Performance \u0026amp; Reliability\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\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 class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\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 class=\"p1\"\u003eWhen you choose Hamilton Cams, you’re investing in proven innovation and superior craftsmanship.
