BOUNDARY Billet Oil Pump Gears w/ MartenWear Treatment [10295 HOUSING] (1999-2015 GM LS)

The Chevy LS billet gearset is a perfect performance upgrade for 10295 and 10296 housings.

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? It gives you a pump with stability over 9000 RPM, proven in excess of 2000whp, with higher efficiency, less friction, and backed by one of the industry's best warranties.

Oil Pump Gear Features:

• Mirror Finished and Surface Hardened
• Surface Ground gears for the ultimate in fitment and performance
• Indestructible Chromoly core
• Inner and outer gear machined in matched sets
• Our race-inspired gerotor design for flow and strength
• 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.
