Amazing that the Chevrolet had auxiliary or helper springs and the Ford did not!

Auxiliary springs where used provide reserve capacity for heavier loads...
...Spring shackle studs are provided with lubrication fittings (except front springs of F-8 and F-15 models)....
...Spring shackle studs used on the front springs of F-8 and F-15 models are of the oilless type and require no lubrication.
