Boundary Pumps Billet Oil Pump Gear H22 I4 2.2L MartenWear Treated

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 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 13,000 RPM, proven in excess of 1000whp, with higher efficiency, less friction, and backed by one of the industries best warranty's.
