Hi, I have a 2001 xj with a rubicon express 5.5 lift. The guy I bought it from put some rear shocks on it that are way to long. They are constitly bottoming out while driving down the highway. I have the rubicon express 5.5 inch rear springs with no blocks, just the wedge to get the rearend at the right angle. Does anyone know the correct lenght for the rear shocks? Thanks
