View Full Version : How much cash do I need?

I finally decided I want to take the next step and add a full cage to my ride. Since it's no longer a daily driver it seems like the next logical thing. I have been learning to weld and have a few buddies willing to help me with the difficult stuff. I already borrowed a pipe bender and MIG welder. Now for the questions. What would be a good DOM diameter and thickness for a rock crawler? I wont be doing any racing, so I don't need some crazy strong cage. How much should I plan to spend on all the tubing? Any advice would be greatly appreciated.

1 1/2" DOM runs about $3.00 a foot.
I just bought 120' for my cage, don't know if that will be enough though.

You may be better off buying a cage kit like T&J's Crawler kit or D&C kits and then adding to it. You may be able to buy straight sticks of tubing cheaper, but if you screw up a bend then you a have wasted (to a certain extent) piece of tubing. If you are inexpierienced with using a bender the learning curve might be a bit expensive.

Thanks for the info. I already sketched out my design on a 3-D modeling software to get a guestimate on length needed. I used 1.5" diameter in my design, so I am glad that you are saying 1.5" is good. I don't need to redo my design. It looks like I am at about 130-140 feet. At my guess, that means I will be spending about $500 on metal. I am adding about 15% beyond what I need since I assume I will be masking a few mistakes.

The only cage kits I have found are ALL internal cages. I am planning on building a primarily exo cage. I plan to have a few cross bars inside but nothing more. I am pretty sure a exo cage kit does not exist. I am completely inexperienced on the bender but the owner will be there assisting me, or maybe it will be more like me assisting him.

If there are any guys out there that have built an exo cage, I would greatly appreciate it if you could post up some pics of it. The more I see the better idea I can get on how good or bad my design is. I have already collected quite a few pics from Jeepforum and a couple from old threads on here but I figured the more ideas I see the better I can design my cage.

whatever you do, mock it up with tape or PVC first!

I thought I found an EXO "kit" online a while back. Maybe it was the C-ROK site or Poison Spider.

Good luck!

heres the back half of an exo cage i saw at a 4wp show in my town the front comes down and ties into the front of the slider and makes a front fender bend and ties into the front bumper, i'll see if i can find any more pics of this jeep

So why not go with HREW instead and save some money?

croks are sexy but if you think about it, after you buy the bumpers and the sliders and the cage your looking at over 2g's easy. like with anything else, you cant just have one thing with out a few other things to go with it

If you go with HREW it'll save you some dough.

I don't want to start the dom vs hrew debate but I have had the chance to work with plenty of both and I will never use HREW for anything anymore, it dents/crushes way too easily in comparison, just going to the metal yard the dom sticks are all intact while most of the hrew sticks are dented on the ends, not to mention I have given both the "hammer" test and was amazed at the difference. It takes way too much time and effort to build stuff out of tubing, to me it is a no brainer. You can tell the differences just bending/cutting/notching the stuff. I would not have a problem using braceing/traingulation from hrew as long as there is no chance for impact denting.

good luck Brad!

Absolute truth here.

Now that I have seen the CROK cage kit I am pretty sure it will not work. Thanks to the mad skills of Skullver I already have some kick ass front and rear bumpers and some nice rock rails. None of it would work with the CROK kit. I would have to do a lot of modifications. At that point, I might as well just build my own cage that ties my bumpers, rails, plates, and frame stiffiners together in a more cohesive way.

I REALLY appreciate everyone's comments and pics. Chris I will definately be taking your advice and going with the DOM tubing. I am rather sure that I will be using 1.5" but I am not sure on the wall thickness yet. If anyone is still out there with some more pics of exo cages, I would love to see them.

haha just for kicks, I went lookin and found this...I know nothing about cages, but it uses bolts over welds.

Not sure I'd try to "go fast" in the desert with this one!

Don't underestimate the strength of that cage!
Very well designed and well thought out. I wouldn't hesitate
to rely on that for some go fast stuff.
If I recall right, the military used that system in thier Cherokees.

Hicks, .120 wall is standard. .188 has been used for those bars that you just know are going to take a beating.

that cage rocks!! i swear if i ever save a 1000 dollars that cage is mine =) drilling a few holes dont bother me nearly as much as cutting 1.5" hole to fit a tube =)

I looked at that cage a while back when I was considering a fully internal cage, but I realized that my style of 4wheelin really calls for an exo cage. I know that it is simply a matter of "when" and not "if" in regards to rolling my rig. There has just been too many times that I have been teetering on 2 wheels. One of these days I am going to put my rig on its side or even roof and I would love to have the confidence that I will simply roll onto some external bars and not end up crushing my doors, roof, hood and all the glass. At this moment a roll over would severly damage my rig. The cost of repairs to get it looking good again would probably surpass the cost of just putting a cage on. With a cage I know that it is a one time cost. With a roll over repair, there is no guarantee it wont happen again the next time I take it out.

It looks like a got some decisions made. I will be going with 1.5" DOM .120" wall. I found a steel place in San Bernardino that sales 24ft pieces for just under $75 a piece. I will need 6 pieces to do the cage. (I hope!) It should cost me about $450. They will also cut them in half for me so I can get the 12' pieces in my vehicle. As soon as I get my funds together I will go down and pick up the material. Now all I need to do I refine my welding skills and pipe bender skills. Once I start the project I will start a new thread with plenty of pics. I have a feeling I am about to get in over my head and will probably have a lot of questions at the beginning of the thread.

Good Luck! Once you get done with yours and are nice and proficient I will bring over mine! :cheers:
