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" by using the optional holes. Made from 1/4 plate steel. Unpainted finish.
