-
Heavy Haul
-
Rugged Terrain & Remote Environments
Aftermarket Seating for the Kenworth C500
The C500’s robust vocational cab typically requires a Standard Profile Suspension Seat. However, due to the demanding environments it operates in, many drivers choose seats equipped with enhanced durability and support features such as:
-
Heavy-Duty Suspension Systems
-
Dual Shock Absorbers
-
Extended Travel Suspension
-
High-Back or Wide-Body Designs
-
Advanced Lumbar & Cushioning Options
These upgrades provide superior comfort and reduce fatigue during long shifts in rough, jarring terrain.
Fitment Considerations:
-
The C500 generally uses a standard bolt pattern, but seat compatibility should always be confirmed against the specific cab build.
