Katech Gen III & IV LSX High-Capacity Wet Sump Oil Pump

Katech Gen III & IV LSX High-Capacity Wet Sump Oil Pump

Increased Oil Flow. Consistent Pressure. Built To Perform.

The Katech Gen III & IV LSX High-Capacity Wet Sump Oil Pump is designed to increase oil flow capacity in LSX engines. Featuring a precision CNC-ported oil inlet, this pump provides 23% more capacity compared to the previous Katech Gen III & IV LS CNC Ported Oil Pump (KAT-A2390).

Each pump starts with a brand new GM-style G-rotor oil pump and is blueprinted and CNC ported to improve inlet flow characteristics. This increase in capacity supports applications requiring greater oil volume than a standard or previously ported pump.

Assembled and inspected using strict quality control procedures, this pump is intended for performance and racing LS engine builds where increased oil supply is required.
