Details:

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 tighter sealing 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 drives. 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

• Inner and outer gear machined in matched sets

• Our own race-inspired gerotor design for flow and strength

• Each set hand, machine, and hardness inspected with Blueprinting Report

• Available with our MartenWear thermal processing for extreme anti-wear and tested to 13,000 RPM for reliability.
