KIRKLAND, Wash. — Kenworth has made aluminum hubs an option on front and rear axles of Class 8 trucks equipped with Bendix air disc brakes.

The company expects the option to be popular for weight-sensitive vocational and on-highway operators. The aluminum hubs shave about 80 lbs of weight per axle compared to traditional iron hubs.

They also offer improved heat rejection dissipation and increased brake pad life, the company says.

The new aluminum hubs will be available with front Bendix ADB22X disc brakes on Dana Spicer steer axles rated up to 14,600 lbs. On rear axles, they are compatible with Bendix ADB22X disc brakes with Dana Spicer rear axles rated up to 23,000 lbs (single), 46,000 lbs (dual) and 69,000 lbs (tridem).
