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 5,000 miles. And the best part: ratio exchanges are free of charge for the first three 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.
