Nissan RB26 Oil Pump Gears

The RB26-OPG throws away the weak asymmetrical rotor design and replaces it with Boundary’s own race-inspired symmetrical gear pattern. It is designed to be a tighter seal and created to be a higher volume, so it will have a slight uptick in idle pressure and mid-range pressure up to the relief valve limit. It also has the designed crankshaft interface, which reduces wear on the crank surfaces and eliminates the need for a crank spline drive. This is a huge benefit as you can simply put the gears in the housing and run them as a stock replacement.

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 own race-inspired gerotor design for flow and strength
• Each set of hands, machine, and hardness is inspected with the Blueprinting Report
• Available with our MartenWear thermal processing for extreme anti-wear and tested to 13,000 RPM for reliability.
