I-Shift
When you drive an I-Shift, you’ll never want to deal with a clutch again. I-Shift lets you concentrate on the task at hand—delivering freight— not on what gear you’re in. It’s easy to use and always ready with the right gear, so missed shifts and sore knees are a thing of the past. With I-Shift, just sit back, get comfortable, and concentrate on your driving.
