Boundary Black Oil Pump Gears - 2011-26 Mustang GT / 2020-22 Shelby GT500 / 2015-17 Mustang / 2015-20 Shelby GT350

When you’re pushing a Coyote or Predator hard, the oiling system has to keep up. Boundary Black Oil Pump Gears are engineered to raise the bar for high-RPM reliability, delivering smoother oil flow and greater stability when it matters most. If your build lives in the upper rev range, these gears are a smart upgrade over stock to help protect your investment.

Boundary’s Black series sets a new standard in gerotor technology with MartenWear super surfaces and ColdFinish treatment for exceptionally low friction and extreme wear resistance. Combined with Boundary’s industry-leading ported gerotor design, these gears improve flow efficiency, reduce cavitation, and cut pumping losses—translating to cooler, better-aerated oil at high RPM. Designed to work with both OEM and billet crankshafts, they’re ready for everything from spirited street use to full race duty.

Features

• MartenWear and ColdFinish surface treatment supports up to 13,000 RPM surface speeds without wear
• Ported gerotor design increases flow area for straighter, more efficient oil movement
• Reduces cavitation to limit oil aeration and foaming
• Improves high-RPM oil flow while lowering pumping losses and oil temperature
• Compatible with all OEM and billet crankshafts
