Boundary Dodge Hemi Oil Pump Gears (HEMI-OPG-15+) - 2015-Present Dodge Hemi V8 / Hellcat 5.7L / 6.4L
If you’re leaning on your Hemi for boost, track time, or sustained high-RPM pulls, the factory oil pump gears are not the place to take chances. Boundary’s HEMI-OPG-15+ gears are built to eliminate that weak link, delivering the strength and oiling efficiency your engine needs when the power and revs climb.
Made in Boundary’s Dallas, Texas facility, these gears start as quenched-and-tempered chromoly billets for an exceptionally tough core. After precision machining, each set receives Boundary’s ColdFlow surface hardening and a mirror finish to reduce friction and improve wear resistance. Advanced porting and a race-inspired, symmetrical-tooth gerotor design increase flow and pressure at high RPM while eliminating common stress points. Every set is matched, surface-ground, and fully inspected with a blueprinting report, providing proven stability past 9,000 RPM and durability for serious horsepower builds.
