Let me see if I can interperet this for you. He's wanting to run full width dana 44s and he wants advice on how to make his frame more rigid. Am I close?

thats what I think too.

For starters take your current frame and get rid of it. Then build a new frame that will be strong enough to take the abuse. Add in a few extra frame crossmembers for rigidity and consider an engine cradle type mount which would tie the frame together under the engine. Look for Geesh's thread about his -5 build up.

I was thinking on removing the original cross members,then making wider ones ,plating them in like toy's frames . Using outboard or offset spring hangers. putting in alow profile removable engine cradle.

You can cut to size and stitch weld 3/16 steel plates to the outside edge of your frame rails all the way back to the firewall making sure not to vertically weld the rear of it all the way across the frame rail. Also you can make cross members to reinforce the frame rigidity underneath the engine and in front of the radiator. The weak points in the CJ frames seems to be in the area of the front spring hangers, (both front and rear) and the visible area in front of the radiator. Sometimes throwing something away and buying a new one isn't practical. We've done the above and it has lasted for several years under sometimes extreme conditions.

some people have more money than time, some have more time than money. I had the later when I started rebuilding my `72 cj5. `72 - `75`s had some of the weakest frames. I welded 3/16" x 1 1/2" strap front to back and top and bottom of my frame. I also supported the frame at the area`s where the spring hangers attach.

I boxed and strapped my origional frame too and then outboarded the springs at all 4 corners on my flatfender. Looking back that was a waste of time and I should have built a new frame from scratch.
