Aftermarket Seating for the Kenworth T170
The OEM Air-Cushion Plus seat provides a good baseline for comfort, but drivers looking for improved ergonomics, durability, or custom features often choose to upgrade.
Fitment Considerations:
- 
The T170 cab supports most standard or mid-profile suspension seats
 - 
Low-profile seats may also be used to maximize headroom
 - 
The factory bolt pattern is typically compatible with major aftermarket seat brands, though mounting hardware may be needed if the truck does not have a flat floor.
 
Recommended Seat Features:
- 
Intermediate or high-back support (for longer route drivers)
