Installed the Yukon 3.31 gears on my 2016 Mustang GT and the car feels smoother than ever. Great balance of highway efficiency and acceleration — no gear noise at all.

Put these gears in my 2017 F‑150 and the towing performance is excellent. Smooth ride, strong pull, and quiet operation. Yukon nailed it again.
