Our Camburg 2.25 full-float rear hubs are a great lower cost option for PreRunners and lighter weight race trucks. They are available in 5 on 5.5" and 6 on 5.5" bolt patterns with 35 or 40 spline drive plates. Our 2.25 lightweight hub design has a wider bearing spread compared to 2.5 GN hubs for increased strength and longevity. We also use larger 7" round material for the hub body for increased strength around the wheel stud area. We CNC machine the hubs in-house from 6061-T6 aluminum, then type II anodize them matte black. We use large 5/8-18 large wheel studs with our tapered a hub-centric center caps that help get the wheel on when you’re out on the race course where time is critical. We supply them with high quality Timken bearings and races along with SKF seals that utilize our bolt-on stainless retainers for added protection and retention. Our drive plates are machined from 4340 chromoly, broached, heat-treated, stress relieved and nickel plated gray for corrosion resistance. Our red brake rotor adapters round out the package with all the necessary hardware, O-rings, etc. and bearing preload spacers. Simple things like drilled head bolts to safety wire the brake rotor adapters on show the attention to detail with our hub kits that you don’t get from other companies. To complete this setup you’ll need our weld-in spindle snouts and our custom spindle nut wrench. Wheels must have 4.25" center-bore and machined for 5/8" wheel studs.
