The Rock Jock’s hallmark is its rotated diff cover mounting face. This feature increases ground clearance and creates a smooth surface across the bottom of the centersection. If and when a rock manages to reach this new Currie fabricated diff cover it will have quite a fight on its hands. The diff cover is fabricated from 1/4-inch-thick steel and also fits on a standard-issue Dana 60 housing. The cover makes a perfect home for a Johnny Joint-equipped suspension pivot.
