Description

By improving oil circulation efficiency, these gears help maintain optimal lubrication and reduce internal engine stress, particularly during high RPM operation. This makes them a crucial component for performance-oriented builds. Constructed with MartenWear and ColdFinish surface treatments, these gears are capable of withstanding up to 13,000 RPM surface speeds without wear. The ported gerotor design increases the flow area, allowing oil to move more freely through the pump. The product includes one set of oil pump gears. These billet oil pump gears are specifically designed for compatibility with 2011–2026 Mustang GT and Dark Horse models. They are compatible with all OEM and billet crankshafts.

MIA's Description

They feature MartenWear and ColdFinish surface treatments for extreme durability and a ported gerotor design to maximize flow area.
