With brute-strong, upfit-accommodating frames, Dodge Ram Chassis Cabs are ready to be customized to work for you. Boasting 50,000 PSI of rear frame steel strength – the strongest in its class for 3500[1] – Chassis Cabs can carry up to 8,890 pounds of payload. With industry-standard 34-inch frame rail spacing, a flat frame rail and c-channel construction, you can upfit your Chassis Cab to handle whatever that payload might be.
Durable limited-slip rear axles help carry the weight too. Axles for single-rear-wheel (SRW) vehicles have a rear Gross Axle Weight Rating (GAWR) of 6,500 pounds. The dual-rear-wheel (DRW) axle features a rear GAWR of 13,500 pounds. Dodge Ram 4500 and 5500 Chassis Cab trucks have an unsurpassed, competition-crushing standard front GAWR of 7,000 pounds.
