Steeda Mustang Differential Cooler Kit (2015-2026)

Hard track sessions push Mustang rear differential temperatures high enough to trigger the car's protective de-rate, which cuts power exactly when you need it, and the heat speeds up wear on the bearings and gears. Steeda's differential cooler kit keeps the diff in its happy range so you can run full sessions at full power.

Race-grade components

The kit uses a Tilton differential fluid pump, the industry standard for race gear oil cooling, along with a dedicated cooler and every hose, fitting and piece of hardware you need.

Factory-style mounting

Steeda's brackets put the pump in the same place as factory-equipped cars, which keeps noise and gear oil smell out of the cabin. The install is reversible if you ever want to return the car to stock.

Proven on Steeda's builds

Steeda runs this kit on its own Q350 EcoBoost and 2024+ HPDE Mustang builds.
