Our 2010 with 90,000 miles was "bottoming out" with heavy load in it. We switched our rear shocks to munroe, but still having the same issue. We are now thinking of buying the Bilstein 5100. Question is, does the 5100 lift the rear up 1 inch? Does that effect the front handling with the OEM shocks still on the front? Alternatively, if you have a different suggestion for shock absorption for our large load, (100 lbs boat on roof, two adults, one kid, camping gear in back) our back end needs help from bottoming out. Xterra doesn't bottom out without the load in it. Thanks in advance.
