579 2.1m cab

The Peterbilt 579 is a Class 8 aerodynamic conventional truck introduced in 2012, designed primarily for fuel-efficient long-haul and regional freight applications. It combines advanced aerodynamics with driver comfort and modern technology.

The 579 is widely used for:

• Long-haul trucking (dry van, refrigerated, flatbed)
• Regional freight
• Fleet operations focused on fuel economy
• Owner-operator highway transport

Cab Type

• Cab Style: Aerodynamic conventional
• Cab Width: Approximately 2.1 meters (83 inches)
• Configurations:
• • Day cab
  • Mid-roof sleeper
  • Raised roof sleeper

Aftermarket Seat Compatibility

The Peterbilt 579 uses a wide cab bolt pattern similar to other Peterbilt wide-body trucks: 6" x 12" bolt pattern

Many aftermarket seats fit with either direct bolt-in or with a specific adaptor plate due to the wider bolt pattern

Installation Notes

• Check for seat height clearance with raised roof sleepers
• Verify wiring harness compatibility if replacing powered or heated seats
• Always confirm adaptor use when switching from narrower cab bolt patterns (like the older 4.65" x 12")
