i got an 86xtra cab . That i am in the process of a SAS. Was planing on temproarly running some 3 inch rancho springs i got for free upon closer inspection found the rears to be block and add-a-leaf , which aint gonna fly. So now i am gonna have to bite the bullet and spend some cash .I was wondering what springs work the best ( marlin, all pro, trailgear) as far a flex and overall price is concrened. I have been looking at the 5 inch springs, and think they will work well with the 36 inch bias IROKs that I plan to run with the fenders off and the bed hacked up

 

I heard marlins new US springs are some of the best you can get.

 

5 inches is too much.....I wouldnt go over 4

 

Remember when you do a sas, if the kit is 5" you will get around 6" of total lift, due to shackles and the front drop hanger.

 

If the truck has blocks theres probably a 90% chance it has a body lift too....putting it even higher...u got a body lift too?

I have the new Marlin US springs and they work great so far
