I have everything ready to go for my zuk mod, I'm looking forward to getting rid of my 4" lift blocks. I'm just not sure if the springs I bought will give me the lift I had with the blocks. I bought the 100lb #14's from Black Magic which is what they recommended, but I want a plan b in case I don't get my truck levelled out. So I'm fishing for what some here may have done with a similar lift, my springs are in pretty good shape, but I'm thinking I can always do the shackle lift..ideas please!?!?!! Thanks!

 

Sounds odd but, you can cut a half coil off and the spring rate goes up. Or you can get spring inserts. And yeah you can alter the rate of the leafs and get abit more out of it also.

 

I've seen the spring inserts, I was also thinking I could use some 2.5" ptfe, I can get some and cut whatever I might need in case the springs don't level the truck out. Makes sense about the cutting a bit off the coil springs to get the rate up, thanks for the help.
