Dodge Ram Chassis Cabs are built with burden-bearing suspension. Their rear suspension features auxiliary spring leaves that support each truck's full-rated load. A five-link coilover front suspension with a wide-mounted design improves handling under heavy loads and provides higher ground clearance.

Just as important, Chassis Cabs boast big braking power. They have the largest brake rotors in their class^[1] and all come with a four-wheel Antilock Brake System (ABS). Dodge Ram 5500 Chassis Cab features best-in-class brake wear^[2] — lasting over three times as long as Ford F-550's brakes — so you'll spend more time on the road and less in the shop. The available class-exclusive^[2], integrated exhaust brake reduces brake fade, prolongs brake life, and provides stopping safety and confidence when hauling heavy loads on downhill grades. An exhaust brake switch is included on properly equipped models.
