HV Oil Pump Dodge 5.7L/6.4L Hemi 09-18

The MELLING HV Oil Pump for Dodge 5.7L/6.4L Hemi (2009–2018) is a high-volume internal wet-sump pump engineered for Mopar Gen III Hemi engines. This pump is designed to deliver increased oil flow rates compared to stock specifications, ensuring consistent pressure and film strength under sustained high-rpm operation, heavy towing, and extreme ambient conditions where standard pumping capacity may fall short.

High-volume pump design increases oil circulation throughout the engine block, cylinder head galleries, and valve train components. This enhanced flow is particularly valuable in modified engines with higher displacement, increased boost, or race-focused valve timing that demand superior lubrication under demanding load. The internal wet-sump configuration integrates directly with the engine's existing oiling system, requiring no external reservoir or plumbing modifications. Fitment is application-specific to Dodge 5.7L and 6.4L Hemi powerplants across the 2009–2018 model range, confirming compatibility with your exact platform before installation.

This pump is ideal for Dodge truck and SUV owners running their Hemi engines in towing, off-road, or performance driving scenarios where engine stress and operating temperatures elevate baseline lubrication demand. Builders preparing Hemi blocks for upgraded fuel systems, supercharging, or nitrous oxide also benefit from the improved oil supply that prevents marginal pressure drops at peak horsepower. MELLING's engineering heritage in OEM-equivalent pump manufacturing ensures dimensional accuracy and internal clearances calibrated for the Hemi's specific oil galleries and bearing design.
