Melling Oil Pump 10355HV Gen IV, High Volume, High Pressure, Each

The Melling 10355HV Oil Pump is a high-performance upgrade designed specifically for GM Gen IV LS-series engines. It delivers a 20% increase in oil flow over standard pumps, making it ideal for high-performance and racing applications that demand enhanced lubrication. This pump also features adjustable high pressure, with a pre-installed +10 psi spring and optional standard and +20 psi springs included, allowing customization to meet specific engine needs. Built with durability in mind, the pump utilizes a hard coat anodized aluminum housing and a phosphate-coated cast iron cover for excellent wear and corrosion resistance. For even greater control, it includes a threaded pressure relief nut, enabling fine-tuned oil pressure adjustment. It’s compatible with engines using a 7/8″ bolt-on oil pickup tube and includes the necessary O-rings for a secure installation. The 10355HV is also suitable for engines equipped with Active Fuel Management (AFM) and Variable Valve Timing (VVT), making it a versatile choice for both stock and modified builds.
