Description

The Melling M452HV is a high volume replacement oil pump designed for Mopar Gen III Hemi engines. It features a standard pressure, high volume rotary design with a cast iron cover and aluminum housing. This pump increases oil flow by an average of 12% over stock, improving oil pressure at idle for dependable performance.

Engineered and assembled to high production standards, it utilizes the latest gear and gerotor technology. The high volume gears are machined to close tolerances for proper engine pressure and efficient operation, with precision-ground end plates for maximum wear resistance. Each pump is individually tested for pressure and flow in conditions that duplicate actual engine operating environments. It includes a gasket or seal and an O-ring.
