Built for F-350 Super Duty dually owners who want serious ground clearance without sacrificing ride quality, this Rough Country 4.5-inch lift kit raises your truck while leveling the front with the rear. It's engineered to accommodate 33–35-inch tires while preserving factory handling and drivability through properly-set caster geometry.

What's included
- Lifted coil springs — raise the front end to match the rear and increase overall ground clearance for bigger tires.

- Transfer case clocking kit — re-indexes the transfer case to maintain proper driveline geometry after the lift.
- Radius arm drop brackets — allow caster to be set correctly, keeping your factory handling and steering feel intact.
- M1 Monotube shock pair (front and rear) — valved for balanced on and off-road performance.
- U-bolt block kit — secures the rear suspension to the frame with heavy-duty hardware.
