xj frame stiffining

[Mike L]

I realize it is an unsafe setup. I was my first attempt at fabing a suspension. Thou mistakes were made, I will not repeat them when I redo the front end this spring.

Just add a track bar. :shocked:

Lonestar, What kind of arms are you using. Also what kind of springs are you using in the rear?

Ah, if you're serious..........no he doesn't.

ah, not serious, thanks tho

Agreed, add a trackbar and call it good.

Sorry man it's the same screen name I use on other sites. It just makes it easier me.

Or, doing something like the T and J stiffeners that tie the suspesnion mounts together. To gain the most stiffness without a cage, my opinion would be to run a strap of 3/16" down the bottom of the frame to protect it, then run a section of boxed or round tubing along the outside of the frame from the leaf spring hanger to the lower control arm mount.

What if you "box" in the rear spring mount (or replace entirely), and then brace it to the angle or boxed frame rail (for the life of me I cant think of the correct term for this) then do something similiar on the front mount.. would that be enough to "Tie" things together. I assume this would still only be one dimentional and the cage would be multidimentional..
I have thought about this in planning rock rails..

I think it's generally accepted that additional structure adds more rigidity than using thicker material on existing structure. An example is a well triangulated cage made from .095 will be more rigid than a minimal cage made from .188 wall. It's the structure....cross braces, triangulation, gussetts, etc.....that add stiffness. This is my opinion, but I think adding an additional tube, either round or boxed, between the two suspension mounts will stiffen the chassis more than adding thickness (additional plating) to the existing frame rails. I believe the existing frame rails need to be plated to keep them from collapsing, mostly on the bottom, but it could actually be easier to add a tube down the side of the frame than it would be to do the work of boxing it in.

T and J seems to get good results from their frame stiffening system, which runs a tube between the mounts. I have boxed tubing running between my mounts, and while I also have a cage, I credit the stiffeners with at least as much stiffening as my minimal cage.

Cool, I meant gussets (could think of it) at the rear spring mounts.. you pose some good points, and I am going to have to go lay under the heep and see what I see.. :viking:

I just picked up my HP44/9" on sunday for $200. The guy took the axels off at the frame so I got the leaf springs with the frame mounts still on them. I also got the radius arms, track bar with frame mount, tie rod and draglink. As soon as I get my next paycheck I'll get some c-channel and start ripping apart the rear end on the xj.
