Though production ceased nearly 20 years ago, the Jeep XJ remains one of the most popular 4x4 SUV's in the off-road market, but despite its classic design and fan-favorite status, there's still room for improvement.The XJ's rear upper shock mount bolts are notorious for breaking off due to the bar pin system and age of the vehicle. When this bolt breaks, there is no way to secure a shock or bar pin eliminator. This can cause a lot of frustration, especially if you're installing a lift kit and encounter this problem near the end of the install.Rough Country's XJ Rear Bar Pin Flag Nut eliminates this problem, offering a much easier system for replacing the broken bolt and lining everything up correctly. To install, simply knock out the factory nuts welded in the unibody, slide Rough Country's Bar Pin Flag Nut into the unibody hole, and use the flag nut handle to easily line up your new mounting point within the unibody recess. This innovative design saves hours of undue stress and makes it much easier to mount a shock or bar pin eliminator. Plus, if you manage to break a bolt on Rough Country's XJ Bar Pin Flag Nut kit, it is much easier to replace. Ships with new hardware and instructions.
