    Who has put steel box tubing under their rockers for body re-enforcement? What dimensions did you use? Any pics? Do they double as rock sliders? Any advise on doing this mod? I'm getting ready to do full convert I think. Thanks!

    I have, Depdog has (he has a write up at http://www.off-road.com/chevy project rock ready ), BigJBear is doing it, Keith has, Steve is in the process or has just finished and will be doing a write up. Few others have done it also.
    I used 4x4. Most otheres are using 3x2. Dep and a few others have also welded side bars on and I'll be doing the same as soon as I get my new wheels on so I can figure the width. Steel is already sitting in the garage.

    I'm lookin to start this project soon too. You guys using 3/16" or 1/4"? Steve Fox (UAV) has posted a pic of his truck and what the frame mounted sliders did to his body when smacked really good. They put a buckle in the right side just in front of the rear fender. He suggests only mounting to the body rails, and cab supports. If you do a search on this topic you should find a thread that I started and got a good response to.

    I did mine out of 3x4 3/16" wall tubing. Boss also did this but used smaller tubing; 3x3 I think. Only reason I used 3/16" tube was that was all that was available in that size. Otherwise; 1/8" would be plenty thick. Mine are welded solid to the body from firewall to rear wheelwell opening. They're also a part of the new subframe system in my front floor area. I cut my entire front floors out & made my own subframing to attach the new 16ga floors to.

    I have a few pics but have yet to scan them. Soon as I get them scanned; I'll get them up.

    BTW; I didn't have mine extend out like Dep & them did cause my rig will have nerfs that lower down, hinging on the frame to double as steps.

    Good Luck

    Yes, and I use 3x3" 1/8" thick....plenty thick is right. 1 1/4x1 1/4-1/8" thick for the steps.
