    In my oopinion, there is no price too expensive when it comes to safety. Expecialy in a vehicle that will orbe carried me, my friends, and familiy. Nothing is to costly when it comes to the lives of others. Even if you just do light duty off roading I would still pay the extra. You never know what may happen off road, or even on road for that matter.

    Tie in struts to the frame and build rocksliders into the struts/cage. Just spoke to my shop today and we are planning along those lines.
    Also will be running cage rails from dash bar to harness bar where I can mount a plate for floor shifter, guages, and switches.

    I can't freakin wait!!!!!!!

    There was a really good post about a week or so ago about DOM and other tube. Look for it. I forgot what the title was. It gave a link to a very indepth discussion on the POR board that really cleared up a lot of misconception about the need for DOM. It's over kill and you can get just as strong tube for less. Also went into welding rod and other related information to cage fabrication.
    I built a cage for mine using the exisitng hoop for right at $200. Mine was pretty simple design. Basicly I made legs that extended back as a family cage and came down behind the rear seat. I have a tie in bar over the top. The front is simular with a cross bar at the top. I couln't figure out how to make a cross bar at the dash that wasn't in the way of something. I may cut the dash out and so something like Stephen Watson did in the future to cure that problem. I also have an issue that I got 2 kids and putting a cross bar behind the front seat posed issues with them getting in and out. My truck is a 75 so to get a shoulder harness in I put tabs on and retro fitted a set of shoulder belts.
    There is a lot to concider. I'm far safer now than I have ever been but yes I could have built it stronger but it would have ment the other problems. You need to weigh your needs. I do slow rides and 99% of the rolls I'm likly to encounter is a slow flop onto the side. For that the cage is more than able to deal with. If I was dune running or High speed cross country then it would not be enough. The need for the cross braces would be greater and I would have to make do with the kids having to climb the cross bar. to get in.

    It's not my damn planet monkey boy!

    Hey Grim, did you put shoulder belts in the back also for the kids? I need to do that since they are only lap belts.

    Nope. My back seats are buckets and due to their location I couldn't get the angle right to make it work. They are not posistioned out to the side enough that I would be hard pressed to find a belt long enough to do the job.
    I run a set of non retractable lap belts for them so they can't squirm around in a way that the belt would not do it's job. That's my fear with kids and retractors is they can't sit still and would always be tugging on the shoulder strap or leaning in a way that the shoulder strap won't be where it needs to be to lock the lap portion. They (well the oldest is big enough the adult belts in some vehicles fit her right and doesn't need a booster In the K5 it works but in My Supra she has to use the booster...figure that one out) are always trying to scoot foward in with retractors in the front seats already. Here is my typical drive when the oldest is in the front seat..."Sit back, Sit up straight, Don't slouch, quit pulling on the belt, sit back sit still and thats before we even get off our street.
    At this point I feel for them the lap is working. They can't change the length easily and get it loose to where it won't do it's job. I positioned the anchors low so they can't get above their hips or let them slide foward. They sit in such a way that in a wreck they can't hit anything but each other.
    I may end up changing it in the future but that's how it is now.
    For the record I feel that GM attaching the shoulder belt to the hard top was just plain a bad idea for a 4x4. Every truck with a removable hard top I have seen lay over even a light lay over if that top hits the ground it's comming apart. That terrifies me. Have one end of the belt attached to a point thats going to break away and the other end attached the floor that wont' give. Somebody could be decapitated in a roll with those belts.

    That's what I'm going through with my 5 yr old, lol. That's in the Accord because he has the high back bucket booster he uses with the shoulder belt. In the truck when he sits in the back he's got those boosters with the front attachment used with a lap belt.

    I've been doing a lot of research into this and my advice would be to skip the DOM and do HREW instead. 58 ft is not much tubing for a full cage all the way to the back. My 1-3/4 HREW in .120 wall was .70 a foot and I bought 132 feet. Instead of doing the DOM, brace the HREW tubing really well. Use triangles since they dissapate the most force. Look at some pics of race cars and you'll understand what I mean. Every big open square needs to be cross braced for a really effective cage. If you spend more of your cash on the bracing and less on overkill tubing, I think you'll be safer and probably happier too. FYI also a misconception about DOM is that it's seamless. It's not. DOM is a seamed tubing, it's just drawn over a mandrell which keeps the dimensions in close tolerance. So your 2" tubing in HREW might be 1.94 in some places, 2.06 in others. It may be .140 wall thickness in some and .120 in others. I think this is about all the variance you'll see, but don't be afraid to ask for tolerances from the manufacturer before you order. From what I've seen, you'll be fine all the way down to .095 (that's what a lot of racers use) if you design and brace the cage well.

    GRIM- i read that post on dom vs. welded (great article) anyone who wants a cage NEEDS to read this, i agree w/ you on the lap belts for kids, they are definatly better.

    96C4 AND 91K5- i also thought about tieing it into the frame and using those braces as a mount for rocksliders, great idea and its somthig i can do a couple weeks down the road since this cage is going to drain me!

    STEVE- my k5 goes in on tues. of next week, should be done by wed. evening. it is going to jimmy at edgewater jeep, i called EVERYBODY in co. and jimmy was the most realistic and down to earth. avalanch wanted 1800 to 3000K, highcountry wanted 1k and nobody else could even do it for 3-weeks! but i am picking up all the tubing, plates, and grade 5's. if you want to see it next week give me a call at (303) 948-3529

    LATEX- that is some really good info, ill probably just do both for safety-- dom and cross bracing.


    4- bfg 35's $600

    1-custom front bumper $359

    4- rancho 9012's $280

    1- full roll cage $750

    colorado k5 knowledge---- PRICELESS !!

    thx for all the info-- j.c.

    i talked to scott but he could'nt get me in for 4 weeks, thanks for those pics, nice cage but it kinda looks like a jungle jim on wheels! just a little too much tubing for me. im also adding an extra cross member to the frame behind the t-case as well as boxing in the frame where it attaches.

    Spend extra and get a good cage.
    Bolt it to the frame.

    This is what we built . 70 feet of tubing

    this is an excellent opportunity for you to incorporate 'extras' into your cage.
    mine has seat mounts, center console, and overhead console mounts. also includes tabs for the safety harnesses front.
    a local frame shop put my cage together using 1 5/8 chromoly tube, strong and light. total cost $900
    some pics...

    MTPockets,

    Nice looking cage. I especially like the seat mounts and the center console mount! Is yours tied to the frame?

    Sweet!
