Compatible with both 28-spline and 31-spline front 8.8" IFS differentials.
These gears will require a matching set of 4.56 rear-end gears for a complete installation on your truck and to avoid driveline damage.
2015-2024 F150 Fitment: this kit can be used with 2015 to 2024 F150s with 8.8" Front IFS differentials, however Ford changed the design of the inner axle seals on the 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024 F150s and the ones included in Yukon's install kit will not work. OEM Inner Axle Seals will need to be sourced from a local Ford dealer for a complete installation.
Optional Yukon Extended Service Plan: Yukon offers an Extended Service Plan for this Front End Gear Set which warrants the parts to be free of defect for as long as you own your vehicle. Choose "yes" from the drop-down menu if you'd like to add the Extended Service Plan to your purchase.
