The hinges have to carry the weight of the ramp regardless of the springs' condition. The hinges may be small in size or had poor welds. A good fabricator should be able to determine and effect a fix, that will eliminate any future problems.
Most tail gates are counter balanced enough, that they can be lifted with one hand. A broken hinge would add to this effort. I would wait until the hinge situation is resolved before you consider any spring changes. The repairs may alleviate the additional resistance.
If they are not now fitted, the fabricator can usually drill and tap holes for the installation of zerk fittings. Grease can then be applied, which will help prevent galling and possible breakage and binding of the hinges.
