Boundary Oil Pump Gears Ford Modular 32-valve V8 4V MM-OPG-4V


Don’t be fooled by cheap gears that are direct copies of the factory design. Boundary gears are optimized for better oil flow and ColdFlow surface finish reduces friction. Boundary focuses on providing the highest quality lubrication systems possible for the automotive industry.


The Ford modular motor is a classic spanning 2 decades of production, and Boundary gears and pumps address one of its key weaknesses. Boundary pumps are made from heat treated 4140 chromoly billets, in house in the Texas facility, Boundary oil pumps are guaranteed for as long as you… or the next guy owns them.


Boundary oil pump gears are 100% manufactured in Dallas, Texas production facility. They start by quenching the chromoly billets from extreme heat and then temper it to tough indestructible core. After machining they apply a 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 1500whp, with higher efficiency, less friction, and backed by one of the industries best warranty’s.
