The Peterbilt 388 and 389 are difficult to differentiate from each other. Why? Because they are basically the same truck from the cab to the back of the truck. The only difference is the length of the hood.
The Peterbilt Model 389 has been the flagship for Peterbilt since it replaced the Peterbilt Model 379 in 2007. The Pete 389, with its classic styling and advanced technology, appeals to young drivers as well as seasoned veterans.
There is no mistaking a Model 389 when it is cruising down the highway. With the availability of high horsepower and choices in transmissions as well as suspensions, the Peterbilt 389 can be custom built to meet the needs of clients.
