Leaf spring, S10 main w/AAL question??

I currently have a 3 inch lift on my 94 xj. It has lift coils in the front and AAL in the rear. The AAL has held up fine over the years. I want to lift it two more inches all the way around. I have a set of skyjacker 2 inch poly boost blocks im putting in the front. I also have a main leaf from a early 90s S10.
Here is the question. Will combining the S10 main with my current XJ springs (including the AAL), give me 2 imore inches of lift? In other words, will it be 5 inch in the rear now?

It might but it won't flex at all, will be extremely stiff with 2 mains and a AAL.

Ok, is it a bad idea to use some 2 inch steel lift blocks? :eyes: :explosion

Yes

just do the full s10 bastard pack and a shackle as needed
