For the ultimate in strength and reliability our CNC machined 1018 steel hubs are virtually bulletproof. Like the aluminum kit, they come with bearings, seals and wheel studs. The bearing races for our big spindles and the studs come already pressed in place. (Weight 6.2 lbs. each, hub and bearings only.) Bare steel 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.)
