2015-2026 Mustang 4.11 Rear End Gear & Install KitThis 4.11 rear-end gear and install kit is perfect for getting faster acceleration in your 2015-2026 Mustang! Your factory gears are built to maximize fuel mileage, which leaves much to be desired in the performance department. A gear change can provide a night and day difference when it comes to launching your S550 or S650 at the track. While these Ford gears do not increase horsepower, they will definitely allow your Mustang to launch harder and quicker! Yukon 8.8" Mustang gears are the choice of championship road racing and drag racing teams around the globe. These IRS rear end gears fit the Ecoboost, V6, and GT models with 8.8" rear ends. This kit includes Yukon 4.11 rear end gears, Ford Performance bearings, shims, gaskets, seals, Royal Purple gear oil, Ford Racing friction modifier, and all of the hardware needed to get them installed. These performance gears do not add horsepower, but will definitely get your Mustang getting off the line faster. Allow your S550 or S650 Mustang to accelerate quicker than ever with this 4.11 rear-end gear kit is an excellent choice to get!
Installation Note- Although the Royal Purple gear oil has friction modifier mixed in, it is still recommended that you use the bottle of Ford Racing friction modifier to supply your Super 8.8" IRS rear end with the proper amount of modifier.
- LMR recommends the 75W140 viscosity for all 2015+ 8.8" differentials as it is appropriate for most climates, fuel economy, and performance.
- 3.15 ratio differential is not compatible with 3.31, 3.55, 3.73, 4.09, and 4.11 ratio gears. Use differential M-4204-M.
