leveling kit help (yes another thread)

After searching for hours, with no internet my phone is killing my eyes.

I have an 05 ext cab. Building around a 285 70, I presume 3 inches is needed. However, I have the 3 leaf pack and need the TSB leaves. I see the fat bob and readylift kits are within my price range. Should I get leaves first, or does this not matter? A sweet tax glitch has awarded me extra cash this check (don't worry its legal), and I would love to order before I blow it haha.

If it matters I would get the longer AAL leaf option with new rear shocks as well.

 

If you are stuck on the spacer lift check out hellbentsteel.com

If not buy bilstien 5100's
