carrier exchange program

Our best-in-class Carrier Exchange Program (CEP) adds great flexibility for dealers and customers. Axle ratios can be exchanged on vehicles with less than 10,000 miles and no more than 120 days in service. And the best part: ratio exchanges are free of charge for the first four units. Also, you can upgrade to any differential lock option offered with proprietary rear axles.* For more information about the Carrier Exchange Program, call or visit your preferred Freightliner or Western Star dealer.
