The hubs feature a fully integrated spindle nut combined with an optimized bearing spacer which retains wheel-end clamp load better than before. PreSet Plus hubs also include ConMet Premium Bearings and a magnetic fill plug on rear axles as standard. Bearing adjustments are eliminated since these hubs are completely assembled before installation.
The hub assemblies are designed for both steer (22,000 lb or less) and drive axles (26,000 lb or less), with either disc or drum brakes. A choice of iron or aluminum is available. By spec’ing aluminum, customers can save more than 20 lb on each hub.
