LOUISVILLE. Kenworth Truck Co. is making ConMet PreSet Plus wheel hubs a standard feature on all Class 8 over-the-road trucks. The announcement was made this week at the Mid-America Trucking Show.

“Kenworth customers will receive better performance and easier general maintenance with ConMet PreSet Plus hubs, which help to further enhance the reliability and serviceability of vehicle wheel ends,” said Kurt Swihart, Kenworth marketing director.

The hubs feature a fully integrated spindle nut combined with an optimized bearing spacer, which retains wheel-end clamp load better than before, Kenworth said. PreSet Plus hubs also include ConMet Premium Bearings and a magnetic fill plug on rear axles as standard. Bearing adjustments are eliminated since PreSet Plus hubs are completely assembled before installation.

ConMet PreSet Plus hub assemblies are designed for both steer (22,000 lbs. or less) and drive axles (26,000 lbs. or less), for disc and drum brakes.

They are available in iron or aluminum. The aluminum versions save 20 lbs. on each hub, Swihart said.
