Our race and championship winning Camburg 2.50 full-float rear hubs are a great setup for race trucks and serious PreRunners. They are available in 5 on 5.5? and 6 on 5.5? bolt patterns along with the larger 6 on 6.5? racing bolt pattern with 35 or 40 spline drive plates. Our 2.50 lightweight rear hub design has a wide bearing spread for increased strength and longevity. We also use larger 7? and 8? round material for the hub body for increased strength around the wheel stud area. We CNC machine the hubs in-house from more expensive and stronger 7075-T6 aluminum, then type II anodize them matte black. Our wheel studs are also machined in-house from 4340 chromoly, then heated-treated, stress relieved and black-oxide coated. They have 5/8-18 threads with an 11/16 shoulder for optimum strength. The tapered hub-centric center caps help get the wheels 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. We cut no corners or costs using the best materials, designs and processes. To complete this setup you’ll need our weld-in spindle snouts and our custom spindle nut wrench.
