Made here in the U.S.A. using a sand casted aluminum/titanium mix. The Silver Cloud features a polished finish and offers both old and new style truck mounting hole patterns. The hangers have more grind area than most trucks. At 10.5 oz. weight, they're great for street use. The 5.0 model hanger is 5" wide in between the inner bearings and 7 3/4" wide, axle to axle.
