The Yukon Gear dropout assembly for Toyota 8-inch rear differentials is a fully assembled third member with a factory-set shim and backlash, 30-spline yoke, and 4.88 gear ratio. This upgraded version includes a Yukon steel spool (1.785 in. journal) for maximum traction and durability, arriving ready to install so the installer only needs to install the third member, bolt the cover, and add fluid.
