The Melling M295 is a standard-volume, standard-pressure replacement oil pump for compatible GM LS-based engines. This pump is commonly used as a factory-style replacement for Gen III and Gen IV LS engines where dependable oil pressure and reliable lubrication are needed without moving to a high-volume or high-pressure pump setup. It is a wet-sump, standard-volume, standard-pressure oil pump for GM Small Block LS applications.
The M295 is a good choice for stock rebuilds, LS swaps, high-mileage engine refreshes, and street-driven LS applications that need a quality replacement oil pump. It is considered a suitable replacement for factory GM oil pump 12586665 and is designed to offer improved resistance to cavitation at higher RPM compared with the original factory pump design.
Compatible with many GM LS-based engines, including select:
Common applications may include LS1, LS2, LS3, LS6, LR4, LM7, LQ4, LQ9, LY2, L20, LH8, LH9, L96, LY6, L92, and similar non-AFM LS engine combinations, depending on the vehicle and oiling system setup.
This pump is generally intended for non-AFM / non-DOD LS applications. Always confirm your engine code, timing cover, oil pan, pickup tube, crank spacing, and oil pump style before ordering. Engines with AFM/DOD may require a different pump, and LS7/LS9 applications may also use different oiling components.
