How do I get the most flex with a 4" lift?

[franco802]

I was going to do 33" tires, 4" rough country springs/shocks up front and ORD 4" shackles for the rear and a 1" block(rear only) to fix the rear sag.

This sound about right?

Yep, but get a zero rate add a leaf instead of a normal block.

And assuming you mean a ORD shackle flip, not longer shackles.

I would go with Tuff country or BDS springs if you want flex.

Theres some chart around here with all the spring flex rates.....but i have no idea where it is.

Yes, that's what I mean

Also, a zero rate is not a leaf right? It looks like a skinny block? I have never seen one before.

Damn, I should just go 6" http://www.suspensionconnection.com/cgi-bin/suscon/167104.html

Pretty good deal!! But then 33's will look to small and i don't want to go 35's because i only have 3.08 gears and weak 10 bolt axles.

To get the most flex out of any suspension you will have to remove the limiting factors. In front find some ford shock towers make sure your brake lines are long enough and remove your swaybar. In the rear once again make sure brake lines are long enough and the shocks are the right length. I have never had a lifted truck where I left the rear shocks alone so I don't know if they limit or not.
