Air Suspension (Optional)
Comfort and Control on Every Route
For customers hauling fragile cargo or needing a lower chassis height for easier loading and unloading, the F-Series offers an available air suspension system. Powered by a 17-CFM air compressor, the system quickly fills the air tanks and suspension air bags for dependable performance.

Engineered for traction, durability, and load-carrying strength, these tire and wheel options keep your truck steady, reliable, and efficient on every route, no matter the cargo.
