I have a 4.5 SJ with rear springs and the rear does not sit level. One side is about 3/4" higher than the other. Also I have 2" daystars on the front and I want to bring the rear up about 1.5" to level it out. I don't want to stack blocks so I was planning on making my own. A solid chunk of steel the size of a block would be hard to find and work with.
I was thinking of making my own blocks with 5"x1/2" strap. I was thinking of making like this illustration from the rear view. Basically 4 pieces of strap welded together eith a hole drilled in the top piece and a hole with a rod welded in in the bottom piece. Would this be strong enough? Do you think I would need to weld front and back caps on it to fully enclose it? Any pros/cons to this idea?
Seriously, does anyone else think this setup would be strong enough? I will probably box it all in just to be on the safe side but I think it will be more that adequate with just the four pieces. The 1/2" plate "block" is stronger than the u bolts, the leaf springs, and probably even the axles. Look at the spring perches on the axle they are only probably 3/16" thick.
I am not saying I am right because I don't know for sure and this post is to get everyone elses opinion but just from looking at the axle setup to me it seems blocks made this way would in no way be the weak link.
I am not just trying to argue with everyone one I just want to make sure I understand everything before I go to working on my truck.
What could break on these blocks? I don't think they are going to collapse vertically. They should easily support 20,000 lbs plus each in the vertical direction. There is not really a force acting on them that would pull them apart vertically.They are not weak in the front to back or side to side direction either. The U-bolts would surely break before the blocks deformed.

i know i wouldnt want to be driving around you if you had them. you really cant compare the blocks strength to the axle, the u bolts, or the spring perches.
if you have your mind set on doing this, it would probaly be better off to get rectangular tubing instead.
but i still think the cost of the materials, your time, and welding supplies would exceed buying a set of lift blocks.
thats unless your making like a 8 lift block, which is totally nuts.
first, the spring pad is very small so it minimizes the stress that it would see.
you can get a racking and caving in from a hollow block. you would be much better off stacking blocks than making this setup. especially since stacking blocks isnt that bad. ive been running them for about a year now.
