Dodge Hemi Oil Pump Gears


SKU: HEMI-OPG Categories: , Tag:

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. 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.
