Boundary Engineering Black Oil Pump Gears (2011-2023 Mustang GT / 2012-2013 Boss 302 / 2015-2020 GT350 / 2015-2017 F-150 / 2020 GT500)

America's muscle car is a blockbuster at the strip, and our pumps are made to keep the camera rolling. These pumps are made from heat treated 4140 chromoly billets, in house, right where the world's best selling muscle car is made, THE USA. Boundary oil pumps are guaranteed for as long as you... or the next guy owns them.

Our release of the Boundary Black series is to set a new precident in Gerotor technology. These new gerotors feature both our MartenWear super surfaces for low friction and high wear capability along with our industry leading ported gerotor designs.

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
