Katech GM Gen III & IV LS CNC Ported Wet Sump Oil Pump

Katech GM Gen III & IV LS CNC Ported Wet Sump Oil Pump 

Reduced Restriction. Stable Oil Control. Built for LS Performance.

The Katech Gen III & IV LS CNC-Ported Wet Sump Oil Pump is built from a brand new GM LS G-rotor oil pump and precision CNC-machined at the oil inlet to reduce restriction and improve oil flow path efficiency.

Each pump is carefully blueprinted and inspected to verify proper internal clearances and consistent operation. The CNC porting process refines the inlet geometry to support efficient oil supply, particularly under high RPM and load conditions where maintaining oil pressure is critical.

Designed for Gen III and Gen IV LS wet sump applications, this pump is intended for high-performance street and racing engines requiring reliable lubrication and oil control.
