Boundary | Ford Barra XR6 Billet oil pump gears

Boundary oil pump gears are 100% manufactured in our Dallas, Texas production facility. We start by quenching our Chromoly billets from extreme heat and then temper them to a tough indestructible core. After machining, we apply our ColdFlow surface hardening process and complete it to a Mirror Finish. This gives you a pump with stability over 9000 RPM, proven in excess of 1500whp, with higher efficiency, less friction, and backed by one of the industry’s best warranties.
