Mustang Oil Pump Gear & Crankshaft Gear Sprocket Kit
Boundary designed this high-performance 2015-2026 Mustang oil pump gear & crankshaft gear sprocket kit to replace the factory gears and sprocket in your S550 Mustang. The factory oil pump gears are known to be the weak link when running higher than normal RPMs due to Cobra Jet manifolds, cams or adding superchargers, nitrous, or turbos. The added horsepower will put more stress on the stock oil pump gears and crankshaft sprocket which could then cause oil pump gear failure, leading to engine failure! Pick up this kit today to get that peace of mind when adding more power to your Coyote motor!

High-Quality Construction
Designed and manufactured right here in the USA, with the oil pump being made from 4140 Chromoly and crankshaft gear sprocket constructed from 4340 Chromoly, they are both heat treated for the ultimate protection! Boundary was able to achieve 50% more strength with their crankshaft gear sprocket over the factory piece by adding an anti-burst ring to the design, which allows you to turn up the power!

Installation Note
Does NOT fit 11-14 truck based 5.0L Coyote oil pumps. The oil pump gears are physically smaller and will not fit.
