YUKON GEAR Ring & Pinion 8.8″, 3.31 ratio (Front Axle) – 2011-2023 F150

YUKON GEAR High Performance Ring & Pinion Gear Set 8.8″ in a 3.31 ratio (Front Axle)

YG F8.8R-331R



Yukon Ring and Pinion sets give you the confidence of knowing you’re running gears designed for the harshest of conditions. Whether it’s on the street, off-road, or at the track; Yukon ring and pinion sets deliver unrivaled performance and quality. Yukon uses the latest designs and manufacturing technologies to provide a quiet running gear that is strong and easy to set 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 2023 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.
