So I had originally planned to set my front Bilsteins when i get them installed to 2.1 inches to level my 2018 Ram. this was based on following measurements: fronts-37 1/4 inches rears-39 3/4 inches So 2.5 spread, Bills at 2.1, .4 inches to spare. Only carry light loads generally, occasional dump runs and no towing. No intent to add a rear spacer or do anything else to the rear end. So tonight, I doublecheck my measurements. no change in the front, no change on right rear side, but pretty much a full tank of fuel and my left side dropped to 39 1/4 inches. so 2 inch spread on the driver side in that case. i usually don't drive with a full tank due to weight but gas is cheap now so i've been filling it up every 3 or 4 days. It gave me pause on my initial plan. So, here's a few things I've thought about: Truck has about 4000 miles on it. Will the front coils and the bullies lose a bit of height over a relatively short period of time? Again, not changing anything else and given all the above- would YOU still stick with 2.1? or 1.4 inches instead. I won't go a bigger tire than the stock 275 60 20 or 275 65 20. Lastly, if down the road i decided to put a spacer in the back, can you change the height of the Bullies while installed? thanks for all thoughts.
