Kenworth adds hub/rotor package option

Kenworth Truck Co is offering its lightweight aluminum hub and Splined Disc rotor package as a front and rear axle option on its Class 8 tractors equipped with Bendix ADB22X air disc brakes. This lightweight air disc brake package features an aluminum hub and the Splined Disc rotor assembly that reduces total wheel-end weight, greatly reduces rotor dynamic stresses, provides improved thermal balance, and offers longer brake life.

The aluminum hub and Splined Disc rotor option can save as much as 35 pounds per wheel end compared with other air disc brakes, which use an iron hub and conventional rotor, on the same typical tractor configuration. Bendix ADB22X also adds longevity to brake components.
