Hey Folks,

I'm adding some angle iron on to my Comanche frame to weld some brackets and stuff to, as well as to protect the bottom side of the frame.

My plan was to sleeve the frame (using 1" od, 9/16"id tubing), but as I was drilling, I discovered that the outter frame rail is actually double walled. I'm using 9/16 bolts. Now I'm wondering if I really need to sleeve as the MJ frame rail appears to be a bit stronger than the XJ. On the back side I had planned on using large custom made fender washers to distribute the load as much as possible

What do you think?.. Will I crush my frame rails, or will I be good without sleeving?

Some pics of my setup are attached

Thanks,
Ryan

It will be a lot stronger if you weld in sleeves, without sleeves I think it will eventually crush in over time with flexing.

it wouldn`t hurt it if you sleved it and you`d have the knowlage that it wont crush

Why not weld the reinforcement to the unibody? It's a little crappy to weld because it galvanized, but a little practice and you'll be alright. It helps if you whip it forward to burn the galvinize out and then come back into your puddle.

I didn't want to weld the plate to the unibody because of the HAZ it would create on the already thin frame as it was. Plus I like the option of removing the plate for whatever reason needed down the road.
Thanks for all your thoughts, I guess I will sleeve it just to be sure.

Thanks
Ryan

What you are installing is a disposable skid plate. I would not weld it in but, bolt it on. Once the plates thickness is to compromised, junk it and put on another one.
