The Yukon Dana 30 disconnect block-off plate lets you bypass the vacuum-actuated front axle disconnect feature on Dana 30 differentials. This listing is for the plate only; it restores a solid connection by blocking the disconnect mechanism. For a complete install kit that includes gasket and axle seals, consider YA W39147-KIT for 27-spline or YA W39147-KIT-30 for 30-spline applications.
