It seems that all Ram 1500s have a Left/Driver's side lean..supposedly from the fuel tank being on the left side.
My truck was off by 3/8"(+/-)Rear and 1/4"Front depending on if the tank was full or empty.
My tank is the smallest 23 gallon tank..I'd be curious how much a full 33 gallon tank leans!
I cut my OEM RIGHT rear spring by ONE FULL ring (and added Airlift bags..which are empty currently) but surprisingly, the Left side is still 1/8"(half tank)-1/4"(Full) low depending on the tank fullness. It baffles me that the full ring didn't side-level it because the rear OEM coil springs are ~3/8" thick and the first 2-3 coils compress flat under weight, so cutting one coil off should have leveled it(?!).
Something else must also be factoring into the cause of the lean, and it must be mechanical leverage of some type(?).
With this being an "every Ram" leans issue, it honestly wouldn't surprise me if this were a factory frame jig issue!! I'd actually love to put one of these new trucks on a jig and have it measured out!
Check out "McBay Performance" on Ebay..they sell 1/2" billet spring spacers for the Ram rear springs..use one on the Left rear. The Eibach springs aren't the problem, so take these with you when you go in and have them put it in right away.
McBay ships super fast!!
