I have a 2007 JKU Rubicon with 3.5 inch Rubicon express lift on it. The lift came with shocks and springs and has been on it for about 12 yrs. I off road a few times a year, nothing crazy. Plan is to install a my Dometic 45 fridge in the back with a storage unit. I might be adding a roof rack later on. I am looking for springs and shocks that are geared for more weight. Of course I still want a good on road and off road ride. Any suggestions
