Aluminium service bodies, skirted flatbeds and gooseneck beds. New units from the manufacturers who build them, and used ones where we have them.
Aluminium is lighter than steel, which goes straight onto your payload for the life of the truck, and it does not rot. It costs more up front and it is harder to repair well if it gets damaged. For a truck working where roads are salted, it usually pays for itself over ten years.
The measurement that decides which body fits is cab to axle, not bed length and not wheelbase. You also need to know whether your chassis is single or dual rear wheel, because a dual wheel chassis needs a wider body.
Send us those two facts and we will tell you exactly which bodies fit. New units are listed as new. Used ones are listed as used.
