Boundary oil pump gears OPG are machined in matched sets, and shipped with blueprinting paperwork. Applications include the 2011-2020 Ford 5.0 Coyote Mustang and F-150 Truck, Ford Cyclone Ecoboost V6 and the Ford Modular 4.6/5.4 engines. Boundary gears have been proven in applications exceeding 400HP per Liter. We have found these gears to be nearly indestructible in all applications, and if you do ever manage to break a set we'll happily replace it for free, Unlike others selling oil pump gears on the side, this is our one and only specialty and we take pride in the fact no one has ever broke a set of our gears.
