When installing lifted rear leaf springs, it's best to rotate the pinion so it points directly at the rear transfer case output flange and use a CV style drive shaft. The best way to rotate the pinion is to cut off the old perches and weld in a new set at the proper angle. Normally the spring pin is installed in the center hole but you can also move the rear axle forward or backward 1 inch by using the optional holes. Made from 1/4 plate steel. Unpainted finish.
