The usable payload of many 4x4 vehicles today is minimal. Additional basic optional equipment along with two or three adult occupants will bring the vehicle close to its legal maximum weight (GVM) in many cases. Add long range fuel tanks, bull bars, winches, side steps, roof racks, recovery gear and a payload of camping equipment or an industrial type custom body and the vehicle will ultimately exceed the Original Equipment allowable Gross Vehicle Mass.
Original Equipment suspension is designed for comfort above all other considerations, thus load carrying and performance can be compromised. Whereas, Ironman 4x4 GVM upgraded suspension systems come with matched components for the ultimate in performance, load carrying and handling.
