Hi-Volume Oil Pump Mopar Gen III Hemi 5.7L/6.4L

The MELLING Hi-Volume Oil Pump for Mopar Gen III Hemi 5.7L/6.4L (Model M452HV) is designed for high-performance and heavy-duty applications. It is particularly beneficial for builders and operators who push their engines to elevated RPM ranges or extended duty cycles, where the factory oil pump may not provide sufficient lubrication and cooling.

This internal wet sump pump enhances oil delivery through increased volumetric flow across the entire operating range, ensuring that critical components receive adequate lubrication under high-load conditions. The M452HV is engineered to maintain pressure and prevent oil starvation, which can lead to issues such as lifter noise and bearing wear.

Ideal for modified 5.7L or 6.4L Hemi engines, this pump is compatible with factory block architecture and addresses the limitations of OEM pumps that prioritize efficiency over capacity. Users engaged in competitive driving, towing, or off-road recovery will find this pump essential for maintaining engine performance and longevity.
