Kenworth Truck Co. announced a 52-inch flat roof sleeper intended for Class 8 crane, pump, car hauler and other applications that may require a low roof.

At the same time, Kenworth made its AG400L rear suspension, at a 6.5-inch ride height, 2 inches lower than previously available.

To support the new application, the W990 model added a right hand-side horizontal tailpipe under the diesel particulate filter (DPF)/selective catalytic reduction (SCR) exhaust system to match the current T680 and T880 model offerings. An underrail DPF/SCR exhaust system is also available on the T680 and T880 models, according to the Kirkland, Wash.-based company, a unit of Paccar Inc.



To further reduce overall truck height, the set forward front axle Kenworth W990 and T880S models have a 5-inch drop front axle option that lowers the front of the truck by 1.5 inches over the standard 3.5-inches drop.

Kenworth low-profile tire options include 275/80R22.5 front tires and 255/70R22.5 rear tires, 295/60R22.5 front and rear tires. The smaller 22.5-inch diameter fuel tanks allow for maximum ground clearance. — Transport Topics
