International improved its severe-service Paystar heavy duty truck by making electronic stability control available on all models; offering factory-installed 8,000-, 13,200- and 20,000-pound lift axles, and making 10 ¼- by 3/8-inch frame rails standard on the 5900 SBA (set-back axle). The MaxxForce 11 and 13 diesel engines will be available in the coming weeks, and the 15-liter will be available late in 2010.
