2011-2016 Duramax LML PPE Cylinder Head Cast Iron (110100105)
Experience Duramax cylinder head perfection with the 2011-2016 Cast Iron Head! Different heat expansion rates between cast-iron engine block and cast-aluminum cylinder head cause head gasket scrubbing and eventually blown head gaskets. Made for performance, these heads can handle the heat without warping, melting, or cracking.
Cast from high-quality alloyed gray iron, the PPE Cylinder Head offers elevated fatigue strength, and heat and creep resistance, which prolongs the cylinder head’s lifespan significantly. PPE Cylinder Heads also share the same heat expansion rate as the stock cast-iron cylinder block – no more blown head gaskets. PPE LML Cylinder Heads also feature cast-in fuel injector cups and solve the OEM injector cup leaking issue.
Discover improved valve train components included in each head. PPE's valves feature premium materials and full nitriding. Experience quicker response at high RPMs and eliminate valve float with the increased spring rate and lighter retainers/locators of the tapered valve springs. Rest assured with superior wear and heat resistance from the powder metal valve seats. The cast-iron construction also adds to the reduction of engine noise.
Whether you've got a busted aluminum cylinder head or just want your Duramax engine to last longer and run smoother, the PPE Cast Iron Cylinder Head is hands down the top pick.
