Howdy Folks ! I am in the process of restoring my 79 CJ5 and am wondering how hard it is to tie in the roll bar to the frame ? I have noticed the kits in the 4WDRVH catalog and all they picture is a bunch of steel plates.I know if I am going to do it , this would be the time . I take it you have to cut the pads off of the factory bar and then add extensions that would go through the fenders in the rear and as well through the floor behind the seats ? If yes, are there large rubber grommets that the roll bar goes through when it passes through the floor/fenders? Do you think this is worth doing ?My Jeep will not be a rock crawler , just a week end trail machine . Your feedback is appreciated , Thanks !!

I dont think the bar protrudes thru the floorboard, you leave the plates inside and sandwiche the body with the additional plates on the OUTSIDE..

Im just wondering what this does to frame/body flex?

I mean does it negate any ride softening effect of rubber body mounts?

It would seem that if the tubing is mounted solidly to the frame and to the tub that much flex would rip something?

what am I missing?

I need to do this too, tie in the front and rear bars..

Hi . Yes , I wonder what it would do to the ride as well . You say you HAVE to do this or you just want to do it ? Just curious as to why someone might HAVE to do this procedure.

I've got the 4wd kit installed and it does stiffen the ride. It works great, but if I were to do it again I'd buy a set of rubber body mounts, or probably a length of the stuff 4wd sells for mounting their tubs, and use a section of it between the two plates at each bolt location. I don't think it would cause any ill effects. Any other opinions on that out there? I'm thinkng about adding another 1/2" body lift and putting this rubber in on my setup when I get a chance, so if you think its a bad idea, by all means let me know.

I feel like I need to do it, since this little CJ5 has the quickest turning radius of anything Ive ever driven, it has a big V8, tall tires, and I plan to drive it hard offroad..

I dont have to do it, but Ill feel alot safer driving it with a good cage around me and the passengers, ive driven LOTS of things, this is the only thing ive ever driven that scares me!

and I havent even driven it yet with the newer/bigger V8, and taller tires...

Hi Jeepgod . So I take it then that you have a plate that bolts under the tub and then tubing that welds to the frame ? You never did explain how it was mounted. So the factory bar and the extensions are never really connected ? And in the rear , for the fender wells , the same thing ? Thanks and sorry for all the questions , just need to decide if it`s all worth it for what I am doing with my CJ .

I built my own Full Roll Cage about a year ago using a newer roll bar and my old roll bar as the front hoop. When I installed it I built some outriggers going to the frame and then sandwiched 1" rubber bushings btween the underside plate and the body, at pretty close to the same area as the stock body mounts. It seems to work well, but I guess you dont really know untill you end up on your lid. It sure makes me feel more secure if nothing else. It was an easy project for anyone who can weld,its built strong, and only cost about $150. See the attached picture.

Send a message to Alec78CJ. We're in the process of doing this in his 78 CJ-7 right now with the factory rollbar and Kentrol kit. He'll be happy to tell you all about it!

I do have the dash pad, but you have to cut off the original floor mount and weld on about a 14" piece at the bottom, I sleeved it and put a small angle at that point. It really fits fine,except for the door handle, it needed about 1/2" cut off to clear the bar. I only leave the stock spreader bar on when there a chance ill have to replace the soft top. Otherwise the two spreaders come off and the window can be dropped with two bolts. I ran an electrical loom up to the center section,it controls my 2 sets of front lights,1 set of rear lights, and 2 sets of rock lights, theres also 2 extra power ports for a spotlight and a dome light. Theres a key switch that can shut the whole thing off so no one can mess with anything if you dont want. I also mount the CB at the very front(you can see the brackets). There are extra wires in the loom in case I want to add something later,and the center sections come out in 3 12"x12" aluminum pieces. the top has a 1/4" steel plate welded for strength.

I used the kit 4wd supplies to do it. It is a plate that bolts onto the original rollbar inside the upper fenderwell sandwiching the body between. Then there is a tube that is welded to the plate and goes down and is welded to the frame. The same type of tube is used for both the front and rear places the roll bar mounts to the tub. If you have a newer style CJ rll bar, the front mount works more like a regular body mount and there is no tubing used. I oversized the original holes in the rollbar to something like 7/16 so the bolts were extra thick. I don't have the front finished yet, but the way it works is the same. Hope I answered what you were asking. email me if I didn't.

I have installed a 95 YJ cage in my CJ and I like what the new JP mag artical did to a TJ. 4 Wheel Supply INC has a front cage that bolts to the dash an I was going to try something simular for my CJ so I can maintain the legroom . I was also intertaining the idea of extending the bar behind the dash to the floor but for now it is all in idea stage. I want to be able to secure windshield to cage in same way other manufactors have also.

Even for mild wheeling you need the full 6 point roll cage. All points can be plate mounted and separated by sidewall cut from an old tire. You should make sure that you make the bottom plate larger than the top plate. If they are the same size they will shear the metal in the floor pan during a rollover. The plates should be bolted together by four 1/2 inch stainless or grade 8 bolts. In your planning you should make sure that placement of the rear underside tube to frame is such that you will not get tire rub during articulation.
Good luck!

I witnessed a rollover on swamp route last summer with a YJ set up like the JP article. We had been discussing the virtues of a sytem like that the night before. After the roll I dont think there were many supporters left. The passenger side down bar, sheared away from it attachment and bent rearward into the passenger seat. It was extremely fortunate he had taken his wife and kids out of the rig before trying the climb. That kit in JP is considered a "Sports Bar" not a "Roll Cage". If your just going for looks go for it,but I wouldnt trust it to protect you unless a lot of structural work is designed into the attachment point.
