Pacific Performance Engineering Diesel Fuel Lift Pumps
Pacific Performance Engineering diesel fuel lift pumps are a key component in a reliable fuel system. Rather than depending on the OEM CP3 to pull fuel from the tank, the PPE diesel fuel lift pumps push fuel through the lines and filter to eliminate the possibility of air being drawn into the system, collapsed hoses and fuel restrictions from occurring. These fuel lift pump kits include pump, mounting bracket, dual 12 V fuel pump relays and a wiring diagram.

Pacific Performance Engineering LB7 Cast Iron Cylinder Heads
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 LB7 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 LB7 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 LB7 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 Race Fuel Pressure Relief Valves
Pacific Performance Engineering race fuel pressure relief valves are designed to replace the stock original. Machined from heat-treated stainless steel, these fittings help maintain fuel rail pressure during heavy engine load conditions. The PPE valves eliminate the potential low pressure DTC codes P1093 or P0087 (during power enrichment) caused by insufficient pressure relief valve spring pressure. Order the model recommended for your application.

Pacific Performance Engineering LLY/LBZ/LMM Cast Iron Cylinder Heads
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.

Pacific Performance Engineering CNC-Ported LLY/LBZ/LMM Cast Iron Cylinder Heads
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).

Pacific Performance Engineering Race Fuel Valve O-Rings
Insufficient pressure from the relief valve spring leads to diagnostic trouble codes you'd rather not see. Pacific Performance Engineering race fuel valve O-rings combine with the stainless steel valve itself to maintain fuel rail pressure during heavy engine load conditions. They block the pressure relief port completely, preventing fuel return to the tank. These Viton® O-rings are made from chemical-resistant rubber--better quality than the OEM O-ring for a longer part life. Eliminate potential low fuel rail pressure DTC codes P1093 and P0087 during power enrichment, courtesy of Pacific Performance Engineering race fuel valve O-rings.
