Boundary Nissan VK56 5.6L DE Billet Oil Pump Gear Set
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 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 over 2000whp, with higher efficiency, less friction, and backed by one of the industry’s best warranties.

MartenWear Heat Treatment
MartenWear heat treatment for ultra-long wear debris resistant surfaces
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.
