386

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
• Note: Knoedler has released an adaptor plate (RR12-PB-000)that allows the occupant to move the seat back in  3, 4, 5 inch increments.  This is a common request that can also be met with plates from Truck Armor or Iowa Customs.
• 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
