Spring Rates

[blublur]

Nu B here. I have a 97 ECSB 2wd. I have already installed a ladder bar/ coil over setup on the rear. The unname company that i ordered the parts from suggested that i use 130lb springs in the rear. the truck now rides like a brick. so my first question would be what spring rate should i be running in the rear.
My second question is i am going to be installing a qa1 coilover conversion setup on the front. the truck is fairly low (5" front/6-7" rear drop). what spring rate should i be looking for for that kit? The truck has 17's on it and it seems to handle fairly well. it currently has a 5.7, but will be recieving a 6.0l within a month or 2.

Thanks in advance

do you have the truck scaled? what is the rear weight? coil-overs generally are not going to give great ride characteristics.

Go 15 or 20 lbs lighter and see how you like it

what about progressive rate springs? what spring rates are people running in a full size truck? i am mainly concerned about the rear rate, because it really rides like a brick, and the suspension moves freely w/o any springs and shocks.
thanks

the truck has never been scaled and i dont have any access to scales. the truck is fairly close to stock weight, minus the stock rear suspension replaced by ladder bar setup w/ coilovers
