Dont use blocks!??!?!?
They will F up your springs. The 2wd leaf is too soft to run a block and will go flat and even W a bit. Trust me. I know. I only ran a 2inch block and a belltech shackle.
Go to a junkyard, and find some expo rear leafs. You can get a set for under $30 from most U-pull yards. They are a much stronger leaf and have a better curve. Truck ends up looking like this if you run a fabtech spindle and 32's...
And to make it even easier, I made a nice write up you can help guide you along... CLICK ME! CLICK ME!
