why would you want to put the composite springs on? ive heard nothing but people bad mouth them, i dont know from experience, as i have the steel ones, but i figured if no one else is gonna at least i will warn you. also i just switched my rear end from a G80 to an open rear instead, if your an off roader invest in a tru-trac or something other than the stock one, if you are just a daily driver posi is just a word, you will never need it and may even regret it, my 99 was missing so many teeth i cant believe it even worked and i am by no means hard on my van so i can oly imagine what a 94s rear end would look like by now.

I've got the fiberglass and overload mine all the time. No evidence of a problem. See my sig.
I was told getting my beauty sleep was a waste of time.

Nothing wrong with fibeglass leafsprings, I put a second set on my 94 EXT and don't need a lft kit, the springs gave it almost 5". And I have hauled as much as a ton of cargo with only about an inch sag under the load. Also mine has a stock posi rear end that take on off roadin with out hesitation.
