I guess I can't see why it wouldn't work.

I used Ford ranger bastard packs for the rear of my jeep. One main, another cut up main, and the rest of the pack.

4" main leaf with stock rest of pack? am i being retarded or would that take some really strong spring clamps? the main would be a rainbow while the stockers would sit flat

To me it depends on how he put the pack together and if the rig is SOA or under? Can you provide a little bit more info?

YJ stock springs are really soft, so the arch from the 4" spring will give arch to the "flat" YJ stock springs, just not the complete 4". Same principle is what I am working with on my build- the S-10 springs I am going to use will give 3" of lift on an XJ, and an XJ spring will give 2" of lift on the YJ- I am hoping for 3-4" of lift my just using the one main leaf from the S-10, but we will see.

It is the same as using an AAL- they will probably not last as long as a full pack, but for the price they work.

Leaf springs get much of the arch from the shorter springs of the pack. I agree with what was said above. If you uses the 4" main with stock leafs, it will be flatter than you would think. In most of the packs I have taken apart, it seem like the stiffest one is the 3rd leaf in the pack (2nd leaf away from the main).

With SOA, the main leaf is the top leaf. It will flex flat until it touches the other springs.
