Kenworth Truck Co. has introduced a new line of aluminum hubs for front and rear axles on its Class 8 trucks and tractors equipped with Bendix ADB22X air disc brakes. The new hubs will reduce nearly 80 lbs per axle from iron hubs and lower operating costs, the company said.

For front applications the aluminum hubs are available with Bendix ADB22X air disc brakes on Dana Spicer rear axles rated up to 14,600 lbs., and for rear applications up to 23,000 lbs. (single), 46,000 lbs. (dual), and 69,000 lbs. (tridem).
