Mounting a rollcage....

    Ok.... soon enough I will be going someplace to get a rollcage put in. Now how should I mount it in? I was really thinking of going the way of going through the flooring and mounting it to the frame. Then mounting my seats to the cage. I have heard good and bad things about doing this... the bad I have heard is it stresses out the frame and could eventually cause stress cracks. That's all I need to crack my frame.... not! So if I don't go with mounting to the frame and mount it to the body, should I weld it in or bolt it in? I'm really looking at ideas of how to do this and what will be easiest, work the best and not cause to be poor for years to come. So any tips, ideas and things I should know would be appreciated!! Thanks!

    Mount it to the body...they make big plates just for this purpose. Bolt it on, attach your seats to it, and wheel like mad.

    You definitely dont want to weld the cage to the sheet metal of your rigs body...when stressed, it'll just tear/break the sheetmetal. You want your seats attached to the cage just in case you have a BAD wreck, and the body seperates from the frame (bad times!)...in that scenario, you'll be secured in your seat, inside the cage, in the body. Hopefully safe. If the body tears off and you are bolted to the frame.... =(

    You can safely mount it to the frame. You just need to use a mounting system that will allow things to give a little instead of cracking. I used urethane bushings on mine, and have pictures posted in the "Suburban Cage" section of my webshots site if you want to take a look. The link below my sig will take you there.[​IMG]

    CCG,
    Did you ever call Bent and Twisted? They do great cage work.

    For my project, we plan on doing the body between plates connected to the frame with bushings.

    It took me quite a few weeks to earn the money to pay the guy that built it for me.[​IMG] I wish I had the talent to build something like that, but I wanted it done right the first time and didn't trust myself with something so critical to safety. He had the Suburban for exactly one month (side job for him, or would've been even faster).

    Thank you. I'm very happy with the final product. The pictures probably don't show it very well, but putting the headliner back in shouldn't be too much trouble. I still have all the windows out, and should be able slide the headliner in through the front window. Alternatively, I could probably slide it in from the rear, before reinstalling the rear A/C unit

    wow 502, that is a bad a$$ cage. How much did it cost you? Looks waaaaay spendy.

    For those of us that will never have a complex cage, mounting the cage securely to the body is cheap and easy, and as noted, if the body seperates, you are still caged. Of course, if you are rich like 502, then go for the uber cage. =p

    Where are they located... I want a place in Sacramento area to do it because when I drop it off my mom will be giving me a ride home. So if it's a drive they won't work!

    For ultimate strength, bolt the cage to the body with 6"x6" plate top and bottom. Then make ties that go from the frame to the bottom plate. You cant make it any stronger this way. NHRA requires you to bolt them in, not weld them on unibody cars becasue it weakens the floorpans. I bolted mine in and havent had any probs yet. I still have to do the frame ties

    In a uni-body car (camaro, firebird, mustang) you have to bolt them to the floor. On some of the older camaros and firebirds you can weld them in because they have a front frame. As for the mustangs try and weld it to the floor and you will go right through the floor, or it will crack th floor the first time you launch. The only place on a mustang you can weld it to the floor is in the trunk area. Thats the way my dad and I have set up all the cages around here and they are all cert. to 7.50

    I have an huge collection of Mustang related images, both road and drag race all are welded in save for pure stock SCCA.

    i had my cage installed by 4wdp's. it was bolted to the body using the plates. it looks good and is functional. they did a good job. better than nothing. for a couple hundred of bucks, can't go wrong.

    I'd seriously perfer bolt in if that is a possiblity. Out of if my floor ever rusted out then I can remove the cage so much easier then if it's welded to the frame. But what it comes down too.... what is safer and will hold up better and not weaken the frame. If welding is better I will go that way... if bolting will work then I will do that... I'm leaning towards this design Steph's Webpage&gt;&lt;&gt;
