Thank you for all the help, springs it will be
If I were you...instead of listening to people on here who have tidbits of information and knowledge I'd call Deaver directly.
I also think the 4" blocks don't sound like the right approach but if you call Deaver and describe what you're trying to do
they will be able to give you expert advice. I recently upgraded the springs on my truck and to my surprise kept the stock block.
Deaver built me a custom set of springs based on what I was trying to accomplish. The custom set was cheaper than their
packaged leaf sets. I do have the KHC torque arm installed so axle wrap wasn't a concern for me. My point is that when you talk about
suspension the people on here mostly have canned answers based on their personal experience, which is fine but my advice is call Deaver and discuss what you're going for and how to you plan to use the truck. Suspension is ALWAYS a compromise between this and that so do yourself a favor and have them evaluate your needs and make a recommendation. If you're wanting to keep the rake then I assume you might want to tow or haul stuff from time to time without squatting. This was my situation as well and the result based on Deaver's advice has been spot on perfect.
