Melling Performance M155 - Factory style GM Oil Pump

Description

Made in the USA to the highest production standards, Melling stock-replacement oil pumps deliver dependable performance and factory-spec oil control every time in every application. Engineered and assembled using high-grade materials, each pump utilizes the latest gear and gerotor technology to guarantee reliable engine lubrication and protection. Internal gears are CNC-machined to close tolerances to maintain correct operating pressure and efficient fluid delivery across all RPM ranges. Precision-ground end plates provide maximum wear resistance against scoring and cavitation, extending pump life and maintaining tight internal clearances. To guarantee complete peace of mind and out-of-the-box reliability, every Melling oil pump is individually bench-tested for flow and pressure under conditions specifically calibrated to duplicate actual engine running environments.
