how much lift should i be getting

I have a 94 fullsize with 22"s and drop control arms and drop spindles will lay out but will hardly get the tires out of the fenders I have slam re 8 in front also have to air up to like 150psi to life is this normal. and should you use drop spindles with drop contol arms. any help would be great thanks

i run 100 psi in front. 150 i am locked solid... i have spindles and thats all. and am on 17s but that doesnt matter. 150 is stupid high psi

im running he8s with stock control arms and at 120 im locked fully and 45 im at ride height but im on 17s also

I can barely get the wheels out from under neath my fenderwell at 150, I need 180 to 200 to max out my control arms. But Im doored. I have drop spindles and 265 35 22.

sounds like your upper cup may  be too small   do you still have quite a bit of pressure in your bag  when your fully laid out?

i think i do, dont think the bag is compressed all the way its the only thing i can think of that would be wrong the upper cup is just the way i got it about 4 inches and i even have about 1 inch of the cup on the bottom mabey ill try adding larger cup on the bottom. I had stock control arms before and was about 2 inches from laying out so got new control arms now not lifting. should i try stock spindles or this a waste of time  

personally id get stock lowers and make them work.  you probably need to notch the frame where the control arm/steering hits.  you can lay on stock arms.   once you do that, then check your cup heights to make sure your bags are fully collapsed when aired out.     ask for some people to send you pics of their set-ups and just duplicate what they have. 

ok not sure if this matters but it is a 3/4 ton conv to half ton but ill give it a try thanks

Are you using cups on the bottom with the drop arms and drop spindles? if so thats your problem.  All you need is stock arms, drop spindles and 2.5" upper cup and 2" lower cup to lay flat and still get at least an inch on top of the fender.post pics of your set up

ok thanks ill give this a try  now what about just using stock spindles instead of  drop spindles?
