Lower your 1947-55 Chevy leaf spring truck with our proven billet 1.75" wide lowering block kit. This kit lowers the rear of your leaf spring truck 2" or 3" without affecting your ride quality. These block kits allow the vehicle's shock angle to remain unchanged from the factory position. Works great with lowered springs to get that slammed look without sacrificing the handling characteristics. Designed to fit 3" diameter axle housing.
