Forged Billet Aluminum Hubs
Forged aluminum hubs are unmatched for strength and weight savings. Premium grade billets are forged into shape under high heat and pressure, then CNC machined for precise fit on each spindle application. Each hub is multi-drilled for 5 on 4.50" and 5 on 4.75" wheel lug patterns. Aluminum backside mounting plates are supplied for solid rotor mounting directly to the hub. The hubs are shipped complete with bearing races installed, new bearings, grease seals, screw-on billet aluminum hub caps, and 1/2-20 RH grade 8 wheel lug studs.
