Oil Pump - GM 5.7/6.0L Gen IV

The Melling Oil Pump - GM 5.7/6.0L Gen IV is an essential component for performance enthusiasts and professional engine builders working on Gen IV LS-series powerplants. It is designed to maintain consistent oil flow, which is crucial for engine longevity, especially in high-stress environments where heat and friction can lead to premature wear.

This internal wet-sump pump offers a reliable solution for those upgrading from a factory unit or replacing a worn component during an engine overhaul. It features a standard volume output and is equipped with a high-pressure relief spring to meet the demands of performance-oriented 5.7 and 6.0-liter blocks. The 7/8-inch inlet design ensures efficient oil pickup from the pan, significantly reducing the risk of cavitation during high-RPM operation.

This oil pump is compatible with a wide range of GM LS-series applications, specifically targeting the Gen IV architecture found in many popular trucks and performance passenger vehicles. By ensuring the lubrication system operates at peak efficiency, it protects vital internal components like bearings and lifters from oil starvation, making it an excellent choice for those looking to enhance engine performance.
