If you are converting to our 12’’ competition brakes, take it one step further with a set of these CNC machined 7075 T6 aircraft-grade aluminum hubs. They come with bearings, seals and wheel studs. The bearing races for our big spindles and the studs come already pressed in place. (Weight 3.2 lbs. each, hub and bearings only.) Bare aluminum finish. (3” competition studs require hollow race style lug nuts; studs can be supplied loose and cut down for use with acorn style lug nuts.)
