Product Features

High-Volume Oil Flow for Demanding Applications

Designed to provide approximately 18% more oil flow than a standard-volume oil pump, the M295HV supports increased oil circulation demands in suitable engine builds. It may be a useful option for high-RPM applications, engine rebuilds, and LS swaps where additional oil volume is needed. This is a high-volume pump, not a high-pressure oil pump.

Gen III LS Engine Compatibility

Designed for select 1997–2007 Gen III LS engines using the LS1, LS2, LS6, LQ4, LQ9, LM7, L59, LR4, and L33 engine codes. Supported engine displacements include 4.8L, 5.3L, 5.7L, and 6.0L. This pump is for non-AFM applications only and is not compatible with AFM/DOD Active Fuel Management engines. Confirm your exact engine code before ordering.

Forged Aluminum Alloy Housing

The pump features a forged aluminum alloy housing designed to provide strength and durability during operation. Its construction supports stable performance in suitable engine applications, making it a practical replacement or upgrade option when a high-volume oil pump is required.

Installation Accessories Included

The package includes one high-volume oil pump, one sealing gasket, and two spacer washers. These included components help simplify installation preparation by providing key replacement-related parts in one package. Confirm that the pump and included accessories match your engine configuration before installation.
