With exclusive features like our patent-pending booster stability system, the C10 booster handles and hauls cargo with exceptional control. And, our patent-pending booster stability system locks the booster axle in a straight position when you’re travelling over 60km/h for safer, easier handling on the highway. It also locks the booster axle and dumps suspension air when backing up straight for safer, easier, and more stable reversing ?— all without you having to leave the cab.
