I looked at the Mopar website, I was trying to find spring lengths from that but could not. I couldn’t figure out the difference in part numbers either.2 dr is less weight than 4dr sport. Go to mopar part diagram and look at part #s
I believe around an inch and a half but depends what the rubicon was fitted with like a hard top or toe package and stuffHow much additional lift does a 4 door rubi springs and shocks give a sport s?
