This is a high-volume replacement oil pump designed for performance LS-series engines. For Corvette use, match the correct model year / engine variant (for example: Corvette C5 / C6 with LS1 / LS2 / LS3).
Key Features & Highlights
-
Delivers 20–25% additional oil volume over standard pumps in many performance applications (depending on model).
-
Many variants come with a high-pressure spring (where noted) to raise maximum oil pressure under load.
-
Built using a proprietary casting process to ensure strength, rigidity, and reliability under high RPM and thermal stress.
-
Each pump is pressure-tested (covering idle and bypass flows) before leaving the factory to validate performance.
-
Compatible with stock-style oil pickup, screen, and housing in many LS engines (for correct models).
-
Gears and internals are precision-machined to maintain close tolerances for efficient oil flow and reduced cavitation.
-
Includes or supports use of a relief valve / spring system to prevent overpressure, often with a stock-rate spring included.
