Description

The Yukon Dropout Assembly is a complete, fully assembled third member designed for Ford 9” differentials. Built by expert Yukon technicians, it comes pre-shimmed and backlashed to specification, ready for installation into your differential housing. Simply bolt on the diff cover, add fluid, and it's ready to go. This dropout assembly features a 3.25 gear ratio and 28 spline count, with an upgraded Trac-Lok clutch-type limited slip differential. This limited slip differential enhances torque bias and traction, providing improved performance. The unit is constructed with a nodular iron case for increased rigidity and power handling, reducing deflection for consistent gear contact and extended service life. Please note that the yoke is not included with this assembly.
