This flys in the face of some manufacturers who seemed to have use the FCA press release to determine what components to use in their suspension, leading to bad or less then desirable performance.Shedding pounds was one goal of the Wrangler redesign, but this maxed-out version crushed the scales to the tune of 4629 pounds. That's 50 pounds heavier than the manual Rubicon and 160 pounds more than the Sahara automatic. More surprising, it's also 121 pounds porkier than a JK Rubicon Unlimited we tested back in 2012.
