The USA Standard Spartan Locker for Dana 44 with 30-spline axles provides a compact lunchbox locker solution that replaces spider gears and delivers mechanical 100% lockup traction. Yukon notes the patent-style spring-and-pin design eases installation and that heat-treated 9310 steel internals add strength. The listing specifies this unit does not fit Jeep JK, so confirm fitment for Dana 44 30-spline applications.
