The Yukon loaded standard open carrier case is built for Super Dana Spicer 70 differentials with 35-spline axles and 4.56+ ratios. Cast and machined to tight tolerances, the loaded carrier is supplied without spider gears in some listings but here is specified for Super 70 35-spline fitment and is intended to deliver correct carrier geometry for high-capacity axle assemblies during rebuilds.
