I designed these things about 3years ago, but never had a lifted XJ to implement them on. Well, things have changed and rather than use a prefab long arm kit I went ahead and made my own. The arms are all 4130, they are adjustable on the vehicle, they use Timken tapered roller bearings that are rated stronger (thrust and radial) and more wear resistant (K factor) than those found in a Dana 35. The bolts are custom ground grade 8 studs. The bearings are retained by heavy duty double retaining rings, I may change this should they prove to not be strong enough. The bearings are also completely sealed from the elements. The swollen area was neccessary in order to fit the bearings that had the properties I wanted. The bushings are OEM Dana units. The bearings allow for unlimited twisting and adjustability as well as taking torque loads away from the rest of the system. They weigh a ton (4130 is stronger not lighter)...I went a bit overboard with the strength, in the future I may have them machined down a bit for weight savings and aesthetics. The whole assemblies are TIG welded for optimal weld penetration and strength. The non mechanical end of the arms are currently at the machine shop getting some last minute modifications, but they are nothing special other than being very heavy walled 4130. The paint is industrial stainless steel coating.
