Improves Acceleration and Towing Capability

The factory gearing on your 2011-2022 F150 may not be cutting it when it comes to your selection of tires or your towing needs. To give your truck a bump in acceleration and keep your F150 in a more effective power band, you'll need this set of Nitro Gear & Axle 3.73 rear end gears. These gears a nice upgrade for F150s equipped with 3.15 or 3.31 factory gearing and helps give your truck some extra mechanical advantage when you towing and hauling and can help compensate for larger tires so that you don't lose acceleration and off-the-line performance due to your changes in final drive ratio.
