Think bigger
A lifted half-ton brings presence but falls short on payload and heavy-duty towing capability. A Super Duty dually can tow, but gives up ride quality, off-road capability and everyday versatility.
Truman starts with a heavy-duty Ford truck, then engineers the suspension, wheels, tires and geometry to work as one complete system.
The result is serious towing capability, real off-road clearance and a controlled everyday ride. Tow Friday. Go off-roading Saturday. Drive it to work Monday.
The Truman difference
Duals out. Wide, military-grade singles in, on high-offset hub-centric rims. You gain the clearance of 41–44 inch tires and keep the payload the truck was rated for.
Sophisticated suspension technology transforms how a heavy-duty truck moves—more composed on the highway, more controlled under load and more capable when the pavement ends.
HD front and rear bumpers, Warn winches, Baja Designs lighting, fender flares, AMP Powerstep XL — specified to work together, painted and finished as one vehicle.
A dedicated project lead, weekly updates and a real person who answers when something needs sorting. You always know exactly where your truck stands.
