Truck capacities are determined by the journal size, not the number of springs. However, typical spring packages on trucks used 4, 5, 6, or even 7 springs, never just 2 like a model truck. Often there were small springs nested within the larger visible ones. Exceptions to this include pedestal type trucks with two springs, like Fox, although even there, what looked like a single spring was in fact several springs nested inside the other. Leaf springs could presumably replace 1 or 2 coil springs, depending on the layout.
