Ya, I hear ya. I have never seen any 6" block either. You could have one made, but that will get pricey quick ! If I were you, I would run the autospring 4" block. Nothing wrong with it. Good company too.
The whole stacking blocks thing, came from when springs had a single pin. Our F150's actually use a double pin, so there is minimal if any movement to be honest. You'd be fine. If you do it, be sure to post pics.
How's it going ?? Anyways, I don't see any issue with changing out those blocks at all. Another option would be an add a lead. Would stiffen up the rear slightly (some people have told me they don't feel it at all). Also gives you a slight boost up. Just another option. I think you may already be running an add a leaf though, huh ? You can always add more. More leafs = stiffer though.
So, you have the factory 2" block, plus your going with the 4", correct ? 6" total in block lift ? Maybe check around for a 6" total height block. That way its only one, and not stacked. Anyways, just some other ideas. I see nothing wrong with what you suggested. And I know how ya feel, I want the deaver pack, but the funds just aren't all there yet, and i have other projects I am trying to crank out. never enough cash to go around ! :lol:
Hey I really like your truck. You have done well. Quick question, I am thinking of doing a similar setup as you. Can I instill the aal and bilsteins before the lift? Or do I have to wait til after to get the right bilsteins? I am currently running 35" Toyo MTs on a leveling kit; 04 FX4. I want to eventually do a 6" and run 37s like you. Thanks man!!
it cost me about 300 bucks, to do the true dual straights with turn downs and to install the 2 hi flow cats and an H-pipe..I am loving the sound man...I get compliments non stop and some say it even has a rough idle sound like a diesel which I am loving. I really think it makes the truck different from all the others. The drone can be bad at sometimes, but I dont know about you, but I always listen to my music really loud.
