The Yukon Dura Grip bare case is a high-strength nodular iron carrier for GM 12‑bolt passenger cars, compatible with 30- and 33-spline axles and 4.10 and up gear ratios. Precision-machined and ready to accept spider gears, clutches, and springs, it provides a stout foundation for limited-slip builds. Note: spider gears are not included; final assembly requires differential components to complete the unit.
