The Econoline Super-Max trailer is the king of the Multi-Max suspension system line with a 16 ton GVWR featuring four of our patented 7000 lbs. axles with a 3 inch - 7 leaf springs system. Each axle comes standard with two solid steel 8-lug wheels with 900x14.5-14 ply tires. The tires have a single load capacity of 3825lbs. This trailer is built to handle the toughest loads and the roughest terrain with the greatest of ease. As with all Multi-Max suspensions, the Super-Max advantages include easy alignment, greater bearing capacity, stronger axles, wider mainframe, lower deck height, and superior load stability.
