Description. Boundary oil pump gears are 100% manufactured in Dallas, Texas. They start by quenching their 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. What does all this give you? First, it gives you a pump with stability over 9000 RPM, proven over 900whp, higher efficiency, less friction, and backed by one of the industry’s best warranties.
Advanced porting to increase flow and pressure at high RPM.
