OEM Duramax cast aluminum cylinder heads fall short over time; the different heat expansion crates between cast iron engine block and cast aluminum cylinder head cause head gasket scrubbing, and eventually blown head gaskets. Aluminum cylinder heads are also prone to warping, melting, and/or cracking in high performance applications where excessive heat is introduced. Pacific Performance Engineering LLY/LBZ/LMM cast iron cylinder heads are the ultimate upgrade to your Duramax engine and eliminate any head gasket or cracking concerns. Cast from high-quality alloyed grey iron, PPE LLY/LBZ/LMM cylinder heads offer elevated fatigue strength and heat and creep resistance, which prolongs the cylinder head's lifespan significantly. They also share the same heat expansion rate as the stock cast iron cylinder block, so no more blown head gaskets. These cylinder heads also feature cast-in fuel injector cups and solve the OEM injector cup leaking issue. Each head comes complete with brand new springs, spring retainers, spring locators, valves, valve seals, valve keepers, valve seats, valve guides, rocker arm dowels, and freeze plugs. Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, the Pacific Performance Engineering LLY/LBZ/LMM cast iron cylinder head is undoubtedly the best choice. Component features and benefits: * Premium 21-4N, Stellite-reinforced exhaust valves, and chrome-silicon alloy intake valves * All valves are fully nitridated with increased abrasion resistance * High-strength, CNC-machined chromoly steel spring retainers and spring locators * Upgraded tapered valve springs provide faster response and eliminate valve float at high rpms * Powdered metal valve seats offer superior wear and heat resistance * Significantly reduced diesel engine clatter compared to the factory aluminum cylinder heads * Increased thermal efficiency compared to aluminum heads * 3-Year Unlimited Mileage Warranty

Pacific Performance Engineering MicroPure Extreme-Performance engine oil filters offer 2.5 times the filtration area of a conventional oil filter, providing the performance your engine oil needs to stay cleaner and for longer periods. Specially engineered synthetic filtration media achieves superior filtration to trap particles down to 5 microns, while a high-powered magnet secured at the bottom of the filter catches metal debris, preventing it from clogging the filter media and prolongs oil life. MicroPure's bypass valve is 10 psi stiffer than the OEM bypass valve and reduces the chance of dirty oil bypassing, and a heat-resistant silicone anti-drain-back valve retains the oil in the filter after the engine is turned off. With increased filtration area, four times finer media, and prolonged filter life, the PPE MicroPure Extreme-Performance filter is the ultimate choice for your engine. Additional features and notes: * 900 sq. in. of premium composite filtration media, a 150 percent increase over stock * Perforated metal core and spiral-wrapped adhesive secures filter media * 3/16 in.-16 UNF threaded baseplate with 47 percent larger passages * Direct replacement for the stock oil filter * High-power internal Neodymium magnet * 50 percent thicker base plate * Withstand 450 psi maximum burst pressure * TorqueStop feature to ensure a tight seal * Reinforced silicone anti-drain-back valve ensures a unidirectional flow

Pacific Performance Engineering Premium high-efficiency engine oil filters offer more than double the surface area of a conventional oil filter and are just what your engine oil needs to stay cleaner, longer. Specially engineered synthetic filtration media achieves superior filtration that catches and holds minute dirt and particle down to 5 microns. A high-power magnet is secured at the bottom of the filter to catch any large metal debris and prevent them from clogging the filter media. The base plate and cannister are both enhanced with thicker materials. With twice the surface area, filtration and filter life of conventional filters, the PPE Premium high-efficiency engine oil filters should be your number one choice for superior oil filter performance.

Pacific Performance Engineering aluminum oil pans offer solutions for your stock engine pan problems. PPE pans are made from high-quality cast aluminum—not steel—for strength and optimum heat dissipation. They're engineered with flat bottoms (no valleys), allowing you to drain all of your engine oil, so no dirty oil is left behind. Also, PPE oil pans hold an extra quart of oil, so you'll see reduced oil temperature, higher oil pressure, and better lubrication to your engine's vital components. These higher capacity deep oil pans are equipped with unshrouded oil pick-ups providing less restriction, resulting in higher oil pressure and better lubrication. The pans include hardened billet stainless steel PPE drain plugs with powerful neodymium magnets that attract and hold ferrous metals, keeping them from damaging your engine's vital internal components. Your stock engine oil pan leaves a lot to be desired. Upgrade to a Pacific Performance Engineering aluminum oil pan.

PPE's CNC-ported LLY/LBZ/LMM cast iron cylinder heads are the ultimate upgrade to your Duramax engine to eliminate any head gasket or cracking concerns. Cast from high-quality alloyed gray iron, the PPE cylinder heads offer elevated fatigue strength, heat, and creep resistance, which prolongs the cylinder head's lifespan significantly. The cylinder heads also share the same heat expansion rate as the stock cast-iron cylinder block—no more blown head gaskets! PPE's CNC-porting process improves airflow, enhancing power, fuel efficiency, and throttle response while reducing engine stress and turbo lag. By smoothing the ports and maintaining wall thickness, these heads provide increased horsepower and torque without sacrificing reliability. Tailored to each specific head, the CNC machining compensates for casting variations, ensuring consistent and optimized airflow dynamics. Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, cast iron cylinder heads from Pacific Performance Engineering are undoubtedly the best choice. Product features: * Specially alloyed gray cast iron liquid-cooled cylinder head * 5-Axis CNC-ported intake and exhaust ports for smooth, unrestricted airflow * Increased thermal efficiency compared to aluminum heads * Reduced noise and vibration, better ride * Eliminates head gasket scrubbing issue (blown head gasket) * Higher fatigue strength and heat resistance * Premium 21-4N, Stellite-reinforced exhaust valves * Fully nitridated valves, better abrasion resistance * Ready to install—comes with all valvetrain components, rocker arm dowels, and freeze plugs * Requires the use of LBZ/LMM glow plugs on LLY engines (sold separately) Important Notes: The valve seats of the PPE heavy cast iron cylinder heads are installed with an interference that maximizes the durability and lifespan of the cylinder heads. Such interference might not be optimal for extreme-performance applications where a significant amount of heat is created. For those applications, PPE suggests that the exhaust valve seats be replaced with higher interference (+0.006 in. to +0.008 in.) oversized exhaust valve seats (Nominal size 34mm).
