they will be too soft. i did rears up front on my rig(crapyota build up) i used a set of 85 4wd rears and added 1 leaf from an 85 2wd they felt alright the first time out( i went kind easy on it). went out yesterday and hamered it and flexed it over every thing in sight. the springs came up into negative arch so much they actualy were catching my pitman arm and stopping my steering( i also need bump stops.) i also added my winch on and when thay are sitting on level ground the right side is kinda going negative not flat any more and no arch. i am gonna add another leaf or two. it is not hard to do. and i got both leaf packs for free so its no worry to play around with them.
