2005-2015

The Peterbilt 386 is a Class 8 aerodynamic conventional truck, introduced in 2006 and produced until around 2015. It served as a transitional design between the traditional styling of the 379/385 and the full aero-body 387, blending classic looks with aerodynamic efficiency.

The 386 was built for both fleet and owner-operator applications, commonly used for:

  • Regional and long-haul freight
  • Dry van and reefer
  • Bulk commodities and tanker
  • Flatbed operations

Its aerodynamic improvements over the 379/385 provided better fuel efficiency without sacrificing durability.

Cab Type

  • Cab Style: Narrow-body aerodynamic conventional
  • Cab Width: ~1.9 meters (75 inches)
  • Available configurations:
    • Day cab
    • Mid-roof sleeper
    • Raised-roof sleeper
  • Shares cab structure with the Peterbilt 384, 385, 378, and 379

Aftermarket Seat Compatibility

The Peterbilt 386 uses the standard vocational bolt pattern: 4.68" x 12"

Most aftermarket seats bolt in directly with no adaptor required.

Installation Notes

  • Adaptor plate is not needed for standard vocational seats
  • In day cab models, check seat height for dash clearance
  • Electrical connections (e.g., sensors or heaters) may require splicing or bypassing if replacing powered OEM seats
