Kenworth Adds 52-Inch Flat Roof Sleeper, Targeted for Low Cab Height Applications

Kenworth introduces a 52-inch flat roof sleeper especially targeted for Class 8 crane, pump, car hauler and other applications that may require a low roof.

With the addition of the 52-inch flat roof sleeper and the Kenworth AG400L rear suspension’s new 6.5-inch ride height – two inches lower than previously available – Kenworth has created a perfect combination for low roof applications. The new specification and sleeper are available for the Kenworth T680, T880 and W990 models.
To support the new application, the W990 added a righthand side horizontal tailpipe under the DPF/SCR to match the current T680 and T880 offering. An under rail DPF/SCR exhaust system is also available on the T680 and T880 models.

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.

Marker lights, beacons, airhorns and vertical stacks are also available, making the Kenworth 52-inch flat roof sleeper an excellent option for image-conscious fleets and truck operators.

The 52-inch flat roof sleeper model is equipped with the 2.1-meter wide cab providing a premium driver experience. Key features include fully trimmed premium interior, 56-inch interior cab height, the sleeper, triple-sealed door for a quiet ride, 15-inch Digital Display, Kenworth SmartWheel® available with cruise and radio control on the steering wheel, and under door light which illuminates the steps and ground. Also available are the latest driver assistance features, including adaptive cruise control and collision mitigation.

In addition, remote PTO controls are available from the factory for easy upfit and a full truck kit provides air and light lines to the end of the frame.

“Truck height is extremely critical in many low-roof operations,” said Laura Bloch, Kenworth assistant general manager for sales and marketing. “The 52-inch flat roof sleeper, plus the other supporting options, will help our customers specify their trucks to meet the needs of their low-profile applications.”
