Billet Oil Pump Gear Chevy LS1 Engine 4.8L 5.3L 5.7L 6.0L Billet Gear Standard Flow Vane Ported MartenWear Treated Boundary Pump

This new gear has the following features:

• MartenWear and ColdFinish combination makes the surface capable of 13000 RPM surface speeds without wear.
• Ported gerotor greatly increases the surface area available for flow and allows the flow to move straight through the outer gerotor instead of having to go up across and down to pumping cavity.

This has many benefits:

• Less cavitation which reduces aeration and foaming of the oil
• More flow at high RPM
• Less pumping losses
• Less heat in the oil
