Billet Oil Pump Gear 420A Mitsubishi Eclipse/ Dodge Neon Boundary Pumps

Boundary oil pump gears are 100 percent manufactured in our Dallas, Texas, production facility. We start by quenching our chromoly billets from extreme heat and then temper it 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? It gives you a pump with stability over 9000 RPM, proven in excess of 900whp, with higher efficiency, less friction, and backed by one of the industry’s best warranties.
