Ford F-150 Final Drive Gear Set - Yukon Gear & Axle - High Performance, 5.38 Ratio - '06-'18. A direct-fit high-performance ring and pinion set engineered for Ford F-150 models from 2006 through 2018, designed for drivers adding power or larger tires who need reliable final-drive gearing.

This Yukon Gear & Axle set uses proven designs and advanced heat treatment to deliver a durable, quiet-running gearset built to OEM fitment standards. Yukon’s optimized tooth surface finish reduces friction and heat under high-load conditions, helping the gears last longer when you increase torque or upgrade tire size. The 5.38 ratio provides stronger final drive torque for towing, off-road use, or enhanced acceleration in modified trucks. Yukon products are manufactured from high-grade steel and undergo in-house testing for consistent quality. The set ships with Yukon’s standard one-year warranty and is eligible for the Y.E.S. lifetime protection plan.
