I own a 46 Studebaker that used to be a drag truck and is still set up that way. When looking at the truck from the rear or front it physically sits lower on the driver's side. I am told this may have been intentionally made this way?

lots of things to check,springs may have settled

Ladder Bar or 4 link put it on the scales and see if it has alot of preload . Could be like stated above springs have settled

Check the frame height on both sides. Possibly the body was just mounted that way.

I can't think of a reason it would be intentional.

I am gonna guess it had preload in the right rear and over the years the left front spring has settled. My old car did the exact thing.
