That’s where AEV’s FX370 turnkey kit for the Ford Super Duty comes in. AEV also claims the FX370 kit was designed to balance daily usability with enhanced off-road capability. AEV doesn’t just see this as an option for off-road toys; it claims the FX370 kit is perfect for commercial users and everyday towing and hauling as well. If you don’t already have a truck to modify, it would be even simpler to head to the dealer and get a Super Duty Tremor. And if the bigger tire still isn’t enough, AEV also offers a kit that puts the Super Duty on 40s.
