G'day, first time poster here. I just got my pickup so I'm still coming up to speed, although I'm a pretty competent mechanic. My off-road experience is based on 1960's Land Rovers.

The truck is an extended cab with a topper on it, and it's currently sitting on some crappy Big-O 32 x 11.5 tires. It's got a saggy butt on it though. I know the front can be jacked up with the torsion spring, so I'm trying to determine if the previous owner (a bit of a loser, mechanically speaking) lifted the front or if I have sagged rear springs.

What should the distance between the center of my wheel to the fender be? Or is there another measurement often used?

If I do want to lift the rear, would building/buying some longer shackles be a legitimate solution? Any ideas of the relationship between the length of the shackle and the amount of lift - ie, 1" longer = 1/2" lift or something like that? Of course, I could put in new rear springs but I kinda need to know what's in there now - I'd hate to install a 2" lift and discover the rear of the truck drops by an inch!

I am planning on going to a 31 x 10.5 BFG. The truck is going to see some off-road use, but nothing major. Just getting into Moab campsites and the like.
