Kenworth is now offering a factory-installed twin-steer configuration for its T880S vocational model. The T880S Twin Steer features a set-forward front axle with a 61-inch axle spread to maximize payload, as well as a very short 114-inch BBC. This allows larger bodies to be installed farther forward and closer to the cab.
The T880S Twin Steer will address applications such as ready mix, block trucks, cranes, and concrete pumpers. Depending on the detailed specs, as well as federal and state bridge laws, the T880S Twin Steer can handle 1,500 or more pounds of additional payload as compared to a non set-back axle twin steer.
The 61-inch axle spread also enables Canadian customers in the provinces of Alberta and British Columbia to get a factory-built T880S Twin Steer that meets Western Canadian tandem axle requirements, specifically for ready-mix application. It also means that the Kenworth T880S chassis can be upfitted much faster, saving between three and six weeks in delivery times.
“We strive to enhance productivity for our customers whenever we can," said Kenworth Marketing Director Kurt Swihart. "Kenworth has a long history of building factory twin steers, including the 72-inch axle spread available on our set-back axle T800 and C500 models."
The Kenworth T880S Twin Steer’s front axles are rated at 40,000 pounds. The front end components, including axles, springs, and steering gears, are shared with the non-twin-steer T880S. The front suspension is “equalized” between the front and rear steer axles for greater driver comfort and payload distribution between the two.
The T880S offers the Paccar MX-11 and MX-13 engines up to 510 hp with torque up to 1,850 lb-ft. An Allison automatic transmission is available when ordered with Paccar wide or standard track front axles.
