Ok I'm building a new suspension for the truck. It has a 700hp BBC and 2.5 ton rockwells. I'm gona end up with about 13"-15" total lift when done(1" ZRs, 3" BL, and rear shackle flip are mandatory). Should I go with a 52" front/52" rear setup, 52" front/56" rear, 52" front/63" rear, 56" front/52" rear, 56" front/56" rear, 56" front/63" rear setup? I'm thinking the 52" front/52" rear setup would probably be best. The truck will be on 46s so I'm thinking of this.

Front would be 6" 52s for 10" suspension, 1" ZR and the 3" BL = 14" which is what I need/want
Rear would be 6" 52s, 4" shackle flip, 1" ZR, and 3" BL = 14" which is what I want/need. Would that be an alright setup?

I know some of you are going to say 14" is too much but I think it would be best.

That is with one ton axles, 39.5s, and a ****tybuilt suspension.
 
I would do 52/56 personally if i was doing springs on rocks. Its going to be be a rough ride with the rocks as is, might as well give it some extra spring to try and dampen it up some.

Links will be your best option especially for rockwells, but i know this isnt an option for everyone.
 
Well with being 19, leaving for the Air Force in June/July, and getting married next December I can't get linked right now.
 
lol, i fullllly understand my friend. im 19 and my blazers sitting in a pasture waiting for me to find a money tree again!
 
Well I think I'm going to do the 52/56 route because with my truck being a short bed I think the 63s will be tooo long for the truck.

Now with going 56s in the rear, with going with the longer spring is it going to give me more lift? I know switching to front 52s will give you about 4" extra lift.
 
My vote is for the 52/63 combo. Better ride, better flex.
Just get some good shocks to go with them.
They shouldn't be too long for your truck. Guys are using them in k5's
 
56-63... if your going that big its the best way to get even a decent amount of movement out of the springs...
 
With 700 hp spring wrap will be an issue with any spring he goes with.

I would go 63s rear and 56s front. More than likely you will need some sort of traction bar in the back so you mine as well have a longer spring. Assuming everything equal longer springs will ride better

x2 exactly my thinking...
 
I'll be building a set of custom traction bars for the rear. Might possibly do a set for the front.
 
x2 for the 64's in the rear. ive just got 5" 64's in the back with a shackle flip and a stock 350tbi, and i definitely need a traction bar to stop axle wrap some times.

There is no lift gain in going from 52-56" springs in the rear. You will need to flip the shackle flip brackets to the opposite side to accomodate to the longer springs.
