Description

The Yukon Dropout Assembly is a fully assembled, ready-to-install differential for Chrysler 8.75” differentials utilizing the 489 case. This unit comes with a 3.73 gear ratio, 30 spline count, and features an upgraded Sure-Grip/Powr-Lok clutch-type limited slip differential for enhanced traction. Please note that the yoke is not included with this assembly and will need to be sourced separately. As a complete dropout assembly, installation is simplified compared to a gear set installation, reducing labor time and complexity. The Sure-Grip/Powr-Lok limited slip differential provides improved performance for both on-road and off-road driving conditions.
