Yukon takes great care to precisely design and manufacture these gears so that your truck can take on just about any job or challenge without getting let down by its driveline. Each set of gears is made out of triple alloy 8620 gear steel which is extremely tough and can handle towing, off-road, and racing applications. The gears are precision cut and machined to be extremely strong while running smoother and quieter than the competition to avoid ruining your truck's street ride. The gears drop right into place of your F150's factory gears, and a Yukon Master Install Kit is available to help give your front differential an overhaul while you have it opened up.

Compatible with both 28-spline and 31-spline front 8.8" IFS differentials.

These gears will require a matching set of 3.73 rear-end gears for a complete installation on your truck and to avoid driveline damage.

2015-2023 F150 Fitment: this kit can be used with 2015 to 2022 F150s with 8.8" Front IFS differentials, however Ford changed the design of the inner axle seals on the 2015-2023 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.
