The Kenworth T600 requires a Standard Profile Seat that can be selected from a variety of aftermarket truck seat manufacturers. Drivers may also choose to select an alternate profile seat in order to meet individual preferences. In these cases, the bolt pattern or footprint of the seat may need customer modification depending on the manufacturer and make of the seat. Seat Specialists offers seats from the top manufacturers and continues to grow the selection based on user reviews and information in the market place. If you do not find the information that you are looking for, feel free to contact us. Always assess the fit of a seat to your truck, as your individual cab may be modified or require a special adaptor plate. Installation of a new truck seat is at the sole discretion of the installer.
