Mustang Oil Pump Gear w/ Grip Surface & Crankshaft Gear Sprocket Kit
Boundary designed this high-performance 2015-2026 Mustang oil pump gear & crankshaft gear sprocket w/ grip surface 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! The Boundary crankshaft timing sprocket with a grip surface improves the durability of the crankshaft snout and keyway by limiting the movement of the harmonic balancer. 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 the crankshaft gear sprocket constructed from 4340 Chromoly, they are both heat-treated for the ultimate protection! The Boundary crankshaft timing sprocket with a grip surface improves the durability of the crankshaft snout and keyway by limiting the movement of the harmonic balancer. After adding this sprocket to your motor, you will be ready to handle high horsepower and high RPM track sessions with peace of mind! Each sprocket undergoes a hot quenching process with a low temper, ensuring maximum strength and resistance to wear.
