Home grown rocker protection?

Post by cobshane »

I'm planning on cutting out my rockers and putting in some skis since mine consist of a lot of fiberglass. Was wondering if any of you have any pics of of yours? or build up pics?<br />I was planning on using 2x6 square tubing. Anyone have any suggestions or other options?

Here's mine. Made from 2x3.5 (I think) 3/16" tube.

Vertical piece is butted against the bottom of the door jam and the horizontal piece against it. The L-shape is very strong. I would like to tie it into the frame with some bushings someday as it's hard on my body to deal with that stress, but so far it's handled it great!!

Exactly what I am looking for. So the vertical piece is butted against the floor pan or the supports? I do like that design, looks beefy. Have you takin some hits with them? Have any up and under pics?

If you have stock rockers you'll see where I butted them once you cut your rockers off. But it was against a vertical wall inside the rocker and butted to the floor pan. I think I recall cutting the supports around these to get them flush to the floor, then welding supports back to these.

I measured down 3/4" below the door sill and made my cut and removed the rockers. Then push the vertical piece into place against the floor. Then level your horizontal piece into place and tack them together. Pull them down, weld them out and go back in for the final install.

My advice is to cut your rockers and do some measuring to get the right size of steel. It's been too long for me to recall the sizes for sure, but I know I am close. You may also want yours to stick out a little further, so maybe your horizontal or vertical piece can be 1/2" wider.

It's taken some huge hits. I think the body is taking the toll around the door opening, which is why I'd fasten them either 100% to the frame or to the body and then to the frame using bushings. The steel is holding up great. The body is where my problems are arising. Either way, look into tucking your bushing as high as you can. Maybe angle the supports off the frame at opposing angles. The idea is to keep the sliders from moving back and forth as well as up and down. Make sure you have nice baseplates to spread the load out on the frame and go the full height of the frame for best support. Our frames are strong, but the metal itself is pretty thin.

Another change I'd make to mine is to seal them up to be air tanks. Even if you don't have OBA, take care to seal them up so you can use them as such later. Also, maybe make them a little shorter than you think because mine rubbed at full stuff in the rear and I had to cut them down ruining all the work I did to make them look finished.

For what they have been thru, they have worked great. I have pivoted my bronco on them many times and with a lot of force at times.

Sorry, I don't have any pictures that I am aware of and my bronco is in storage while I am in Germany for the next three years.

Here's the best I can do, but it doesn't show you much other than they are still straight even after 5 years of abuse.

Thank you for all the info. On your build. I can't wait to get started. Ya I was planning on using them as air tanks as well. That definitely will come in handy. Using bushing to frame is definitely a great idea. I have seen some just welded strait to the frame and that has got to be stressful on the body and frame.
If ya don't mind, I might contact you some more during my build, Thank you again.
