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 them 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? First, it gives you a pump with stability over 9000 RPM, proven over 900whp, higher efficiency, less friction, and backed by one of the industry's best warranties.
Features:
- Advanced porting to increase flow and pressure at high RPM.
- Mirror Finished and Surface Hardened
- Surface Ground gears for the ultimate in fitment and performance
- Indestructible core
- Inner and outer gear set included
- Unique race-inspired gerotor design
- Symmetrical tooth profile eliminates the gear's weak spot making our gear sets indestructible.
- Each set hand, machine, and hardness inspected with Blueprinting Report
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 proven to be wear-free in all applications up to and beyond 13000 RPM.
