Like the title says, what is the lowest lift height possible, and what suspension would it be? I'd like as close to stock 4x4 height as possible. I want to avoid the RSK height, so I am wondering about converting an OBS Dana 60 to coil spring?
Also want to stick with OBS axles and 8x6.5" pattern by the way.

Thanks!

OBS axle and coil springs. Barf.

Seriously consider upgrading to an 05+ axle with coil springs. Much more HD axle, brakes, u joints, better steering angle, etc.. My truck was 2" taller than stock after i put in the 08 axle, but that only left about 3" of bump travel. 8x6.5 pattern is easy to achieve with the 05+ axle as well with a drill press and some patience, or take the hubs and rotors to a machine shop.

If I buy this truck, it's got a mint set of factory Alcoas on it. I want to lift it the minimum height to make it 4x4 with a decent ride, that's it.

Really don't want to run spacers or drilled hubs either, not on this truck anyways.

How do you plan on doing the coil Spring on the OBS? Full 4 link?

Also, just in my opinion, there absolutely nothing wrong with redrilling the bolt pattern. The flanges are ridiculously thick, and I pull my 22k lbs 5th wheel with it quite often.

Well, the truck sold before I could make up my mind. Scratch this idea...

It was a mint Centurion, almost identical to what my grandpa had when I was a kid. Would have been awesome to relive some memories in his truck's clone.

Truck was originally 2wd.

Sky mfg 2.5" rsk, low pro rear hangers, and stock OBS f350 front leafs. Factory 4" rear block from a 4wd f350. Sits perfectly level and is on stock size 235/85r16 tires.

This has also been done with no RSK and using stock 99-04 front leaf springs. It was written up on Pirate 4x4 I believe. Custom welded in shackles at the front of the frame are needed. Completely flat leaf springs get shorter when compressed so the front mounted shackles are fine. Gives stock OBS height and the ride of a 99-04.
