Well one of my roll cage designs got a good test. I should say that I did not personally bend and weld this cage. It is a copy of the cage that I designed for my jeep. I always have considered this cage; and my own cage to be the bare minimum when it comes to safety. A solid compromise between space, function and safety. Steve was driving his 71 the other night without the swaybar hooked up. The combo of an S turn, soft RR spring kit, no swaybar and about 45-50 mph was all it took. Earlier in the day I took a short ride with Steve. We discussed the necessity for the swaybar while street driving. Later that evening he rolled his jeep about a mile from my shop. Let me start off by saying that Steve is just fine. He was sore for several days and has a knot on his head from hitting the ground.....road rash on his left arm.... a bruised ego...... but he overall is fine. He is extremely lucky to be alive. We think his head just barley hit the pavement as the jeep rolled. Miraculously the jeep came to rest on its wheels with the left rear tire blown off the bead. Steve believes that the jeep only made one barrel roll rotation, but I think it may have been two rotations judging by where he came to rest in the gravel. After the initial shock and collection his emotions Steve picked up the contents of his jeep. The passenger seat, which was attached to the factory brackets, flew out at some point along with tools, flashlights, blankets, dog... ect. His dog appears to be just fine and she jumped right back in the jeep after it came to a rest. We are still in disbelief that the jeep came to rest on its wheels. After cleaning up his yard sale he reached for the key and the jeep fired right up! The pictures do not even begin to show the damage. The dents on the front of the hood are fresh from the wreck. There is lots of road rash on the top of the cage. Front bumper is 1/4" channel and was straight.... but now has a nice swept back look on each side. The body sides have a little crease on both the drivers and passenger door openings. Window frame is racked pretty good, but I think I can save it. It really is allot worse than the pictures show. Replacement window frame for new cage mock up/ fabrication. Some things I would like you all to see. The front hoop is attached to both the floor and dash. The dash tie in really seems to support the entire system. I first did this to my jeep and it noticeably stiffened up the body. This cage was not yet finished. Large 5" gussets were waiting to be added to the intersection of the front hoop and spreader bars that run front to rear. (My cage has these large gussets in all corners) The main hoop was 2" .120 wall DOM. The front and far rear bars were 1.5" .095. DOM. The replacement cage will be built with a front hoop of 1.5" .120 wall and the gussets will be added from the get go. All in all we are happy with the performance of the cage. Steve lived and walked away. The cage absorbed the impact forces of a good speed roll over. I do question his claim of 45-50mph speed. It would take a good deal of speed to make a complete revolution and land on your wheels. Knowing how Steve drove this thing...... a 60 mph number would be believable..... ....his speedo cable has been broken for a while. Steve now understands my affinity for swaybars on the street. This post could easily have been a RIP..... Just trying to share our experiences and make everyone a little safer.
