Which 63'' springs?

[UrbanRedneckKid]

I need to know which 63'' springs I should buy to match my front lift.

The front is a D44, 5.5 progressive EB springs, stock buckets.

The rear(as of now) I plan to move the front mount forward on the same level not up or down, and I wanna use the 7'' UDSR shackles from www.diy4x.com
(site is mostly GM stuff, but they do have things we can utilise)

So given that, which of my options, 0/3.5/5.5 lift, will get me close to the amount of front lift?

i'm going with the procomp 5.5" which will give around 8" with the factory shackles. i have pretty much the same set-up your going with.

Yup, I've got the 5.5" ProComp's and they're perfect for the 5.5" coil height without any extra block/shackle.
