Aftermarket Seating for the Kenworth K100
Upgrading the seat in a Kenworth K100 can dramatically improve comfort—especially given the stiffer ride and limited cabin space of traditional COE trucks.
Fitment Considerations:
-
The K100 typically uses low- to mid-profile seats due to its limited headroom and cab height.
-
Standard bolt patterns were used in most K100 models, but variations exist, especially in custom or rebuilt cabs.
-
Floor contours and seat base height should be carefully measured—older cabover floors may require shims or custom risers to accommodate modern suspension seats.
Recommended Features for K100 Seat Upgrades:
-
Low-profile suspension system
-
Compact or short backrest design
-
Narrow seat width options to fit the confined cab layout
-
Air lumbar and adjustable dampening to reduce fatigue
-
Swivel base (if cab allows) for improved entry/exit
Important Note:
Some K100 restorations may involve updated floors, interior kits, or seat brackets. Always measure and compare the mounting footprint and clearance before purchasing a new seat.
