Kenworth T280 — Premium Comfort in a Medium-Duty Workhorse

The Kenworth T280 is a modern Class 6–7 straight truck that delivers the comfort and build quality of Kenworth’s heavy-duty lineup in a medium-duty platform. Built on the next-generation 2.1-meter cab, it offers excellent visibility, enhanced ergonomics, and more space than previous models—making it ideal for regional delivery, service, and municipal operations.

Key Specs:

  • Class 6–7 Medium-Duty Truck

  • 109" BBC

  • Built on Kenworth’s 2.1m wide cab platform

  • Straight truck configuration

  • Ideal for:
    Pickup & Delivery
    Service Bodies & Utility Work
    Refrigerated or Dry Freight
    Municipal and Landscaping Fleets


OEM Seating

The T280 typically comes equipped with a Kenworth Air-Cushion or Air-Cushion Plus Intermediate Back Driver Seat as standard, offering basic suspension and comfort for daily driving needs.


Aftermarket Seating for the Kenworth T280

The wider 2.1m cab opens the door to more spacious and ergonomic seating options. Upgrading to an aftermarket suspension seat enhances driver comfort, reduces fatigue, and improves long-term back support—especially for fleet operators or regional routes.

Fitment & Compatibility:

  • Compatible with standard-profile or mid-profile suspension seats

  • Uses the same Kenworth bolt pattern shared with other 2.1m cab models like the T680 and T880

  • Aftermarket seats from 2013+ may require an adapter plate with integrated seatbelt tethers (especially when replacing OEM Gramag seats)

Recommended Features for Seat Upgrades:

  • Air suspension system for superior ride comfort

  • High-back with adjustable lumbar and bolsters

  • Wide or standard-width seat options (thanks to wider cab)

  • Heated and cooled seat options

  • Swivel base or extended travel models (if added maneuverability is needed)


Note on Installation: If your T280 is equipped with a Gramag seat (2013 and later), upgrading to an aftermarket seat will require a tethered adapter plate to meet safety compliance. Always verify seatbelt integration and mounting clearance before final installation.

Seat Specialists offers a curated selection of seating solutions compatible with the T280, sourced from the most trusted brands in commercial truck seating.


The Kenworth T280 was designed for comfort—make sure your seat keeps up.
