Abstract: In a driven vehicle having a drive assembly including a drive shaft, a differential, a rear universal joint coupling the drive shaft to the differential, the drive shaft being characterized by an original angle with respect to the horizontal axis of the differential, a rear axle, a rear axle housing, and rear suspension springs in connection therewith, support blocks for differentially displacing the axle and the housing from the suspension means and restoring substantially the original angle of the drive shaft relative to the differential and to the axle housing while elevating the rear body of the vehicle for maintaining increased rear vehicle road clearance and optimum effectiveness of the drive assembly operation. The support blocks, interposed between the suspension spring and the housing, have top and bottom surfaces oppositely congruent to the bottom surface of the suspension means and the upper surface of the housing, respectively.
