Description
Engineered as the dedicated high-performance upgrade to the popular M342HV, this Melling high-performance oil pump delivers dependable lubrication under demanding RPM and high-load conditions. Designed specifically for performance-built Chrysler, Dodge, Jeep, and Ram Gen III Hemi engines, this pump displaces 20% higher oil volume than stock to support auxiliary cooling lines, remote filters, and looser race bearing clearances. The lightweight cast aluminum housing features an anodized hard-coated body and cover for exceptional resistance to wear, cavitation, and internal friction. Driven by an exclusive high-performance rotor set, the pump comes pre-assembled with a high-pressure relief spring and a serviceable threaded pressure relief nut in place of standard press-in cup plugs. An interchangeable stock-pressure relief spring and an oil pump screen mounting O-ring are included for easy, leak-free installation with factory-style bolt-on pickup screens.
