Kenworth has introduced a 52-inch flat roof sleeper, which has been specially made to target Class 8 crane, pump, and car haulers, as well as 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, industry workers can find the ideal combination for low roof applications. The new specification and sleeper are available for Kenworth T680, T880, and W990 models.

To further reduce the truck’s overall 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-inch drop. 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.

To support the new application, the W990 has an additional 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.


Marker lights, beacons, airhorns and vertical stacks are also available, helpful for image-conscious fleets and truck operators.

“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.”
