BOUNDARY Billet Oil Pump Gears w/ MartenWear Treatment (2009-2011 Nissan GT-R & 2004-2015 Nissan Titan 5.6L V8)

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 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 9000 RPM, proven in excess of 1000whp, with higher efficiency, less friction, and backed by one of the industry's best warranties.

Our MartenWear process developed and applied all in house is a 2nd stage of heat treatment to our billet components. MartenWear heat treats the exterior surface of the part to be extremely hard and long wearing. This surface is more robust against debris ingestion and has been found to be wear free in all applications up to and beyond 13000 RPM. This process is available for most of our steel billet components.
