When it comes to lifting a Ford F-450, you’ve got to make sure that the conversion kit can do the job right. Kelderman, known for quality engineered air ride suspension kits for light and medium duty trucks, has now developed both air and non-air lift kits for the 450 Ford Super Duty, giving the consumer more options than ever for this class 4 truck.

First, there's a non-air system for front and back, designed to be purchased separately or together. For the ultimate in over the road cab comfort, easier loading and towing capacity, consider adding Kelderman’s 4” air ride in the rear, or both in the front and rear.
