Oil Pump & Screen Kit 6.4L Gen III Hemi 14-21

The Oil Pump & Screen Kit 6.4L Gen III Hemi 14-21 is the factory-engineered circulation system designed for Chrysler's legendary 6.4-liter Gen III Hemi engine platform, covering model years 2014 through 2021. Whether you're maintaining a Ram truck, Dodge performance vehicle, or Jeep powered by this displacement, this kit delivers consistent oil delivery to critical engine components. Field-proven across law enforcement interceptor fleets, heavy-duty contractor equipment, and military-adjacent logistics vehicles, this pump assembly ensures engine longevity under sustained operational stress and extreme duty cycles.

The Melling M462-388S assembly integrates both the pump body and protective intake screen in a single drop-in unit, eliminating assembly complexity and reducing failure points common in field repairs. The screen component filters particulate matter and debris before they reach bearing surfaces, protecting against premature wear of the crankshaft, rod journals, and upper engine gallery passages. Machined to OEM specifications with factory-matched tolerances, this kit maintains precise flow rates and pressure regulation essential for the Hemi's high-compression combustion geometry and variable-displacement VVT systems.

Installation applies directly to 2014–2021 Chrysler 6.4L Gen III Hemi applications without modification or adapter plates. Mechanics and technicians performing routine service, engine rebuild, or warranty-level maintenance will find this kit compatible with factory pan gaskets and stock mounting points. At 5.56 pounds and compact enough for standard engine bay access, replacement is straightforward for operators with basic mechanical proficiency; professional installation recommended for first-time users to ensure proper screen seating and pump orientation.
