2009-2013
The Peterbilt 388 is a Class 8 traditional long-hood truck, produced from 2007 to 2015, and succeeded the legendary 379 as Peterbilt’s premium owner-operator and heavy-haul model. It retained the classic long-nose styling while incorporating modern updates like an aluminum hood and improved visibility.
The 388 is built for power and durability, making it ideal for:
- Heavy haul
- Flatbed and step deck
- Tanker
- Agricultural and livestock transport
- Construction (lowboy, dump, and heavy vocational bodies)
- Owner-operator long-haul
With its set-forward front axle and steel/aluminum chassis options, the 388 is suited to demanding vocational and hauling applications.
Cab Type
- Cab Style: Narrow-body traditional cab
- Cab Width: ~1.9 meters (75 inches)
- Available configurations:
- Day cab
- Mid-roof sleeper
- Raised-roof sleeper
- Shares cab structure with Peterbilt 378, 379, and 386
Aftermarket Seat Compatibility
The Peterbilt 388 uses the standard vocational bolt pattern: 4.68" x 12"
Most aftermarket seats will bolt in directly without requiring an adaptor.
