Drive On

The Powertrain Limited Warranty covers the cost of repairs on all covered powertrain components — engine, transmission and drive system — for most new Ram vehicles. Coverage also includes complimentary towing to the nearest Chrysler, Dodge, Jeep® or Ram dealer, if necessary. The warranty is transferable too, so if you sell your vehicle during the warranty period, the new owner will be covered. Plus, our 3-Year/36,000-Mile Basic Limited Warranty provides bumper-to-bumper coverage of your vehicle, from the body to the electrical system.

The 2021 Ram Chassis Cab lets you cruise with confidence. With available Adaptive Cruise Control with Stop this truck can maintain a preset distance, selected by the driver, from vehicles in the lane ahead.
