Melling Performance 10452HV - High Volume Performance Oil Pump for 09+ 5.7L 6.2L and 6.4L HEMI engines

Description

Made in the USA to the highest production standards, Melling high-performance oil pumps deliver dependable performance every time in every application under the toughest RPM conditions. The Melling 10452HV high-performance oil pump is engineered as a high-volume, high-pressure performance upgrade for the 10452 (and OEM M452), delivering a 20% increase in oil volume displacement. This added volume ensures continuous lubrication for demanding performance applications, auxiliary oil coolers, remote filter systems, and engines with increased bearing clearances. The 10452HV features an anodized hard-coated aluminum body and a cast iron phosphate-coated cover for superior wear resistance, reduced friction, and long-term durability. The pressure relief valve incorporates a threaded pressure relief nut and a serviceable screw-in plug rather than a standard press-in cup plug, allowing easy adjustment of bypass pressure. It arrives pre-assembled with a high-pressure (+10 PSI) spring installed and includes an optional standard-pressure spring, along with a replacement O-ring for the oil pickup tube assembly. Every Melling high-performance oil pump is individually tested for pressure and flow under actual engine operating conditions before leaving the factory.

Features & Technical Highlights:

• 20% High-Volume Capacity: Delivers 20% more oil volume than the standard M452 and 10452 pumps to supply sufficient oil volume for high-demand performance engines, external coolers, and looser bearing clearances.
• Dual-Stage Relief Spring Tuning: Comes assembled with a high-pressure (+10 PSI) spring installed and includes an optional standard-pressure spring to fine-tune system pressure to your build requirements.
• Threaded Pressure Relief Nut & Plug: Features a threaded relief nut and screw-in valve plug rather than a press-fit cup plug, ensuring positive retention and easy servicing.
• Hardcoat Anodized Aluminum Housing: Precision CNC-machined aluminum body features a wear-resistant hardcoat anodized finish to prevent bore scoring and internal wear.
• Phosphate-Coated Cast Iron Cover: Rigid cast iron end cover minimizes deflection under heavy hydraulic pressure and protects against rotor galling.
• Factory Pickup Compatibility: Compatible with a standard 7/8" bolt-on screen and utilizes a stock 1.0" diameter bolt-on oil pickup tube.
• Pickup Tube O-Ring Included: Packaged complete with the replacement oil pickup tube O-ring and mounting seals for an airtight, leak-free installation.
• 100% Factory Bench Tested: Individually tested by Melling for real-world flow and pressure performance under actual engine operating conditions prior to packaging.
