Talking Nissan here:
Get Lt 275 - 15's tires (I run Bridgestone Revos), do a 2" lift and crank the torsion bars a little (still can align it OK). You will get 3 - almost 4" don't buy a suspension kit buy separate poly blocks off ebay and buy bolts at local store (nut bolt bin), (American fine threaded fits perfect and cost less) ......get all for about $100.00. Install in about 4 hours. Skid plate, cut pattern out of cardboard and take to the local steel fab shop. I actually just got a piece of plate steel, made the pattern, cut it out with recipsaw. Get the shrockworks rocker guards, front radiator skid they save you in Moab. Also a front tow hook (chevy one fits easily). Get a LSD for the front (from 4x4parts). Been doing Nissans for 20 years. Current is a 02 Frontier, 04 Xterra. Have run both across Hells Revenge, Steelbender, Fins, Kane, etc....go anywhere I care to drive. Of course you can have the best and still get stuck......gotta know how to drive the rough stuff as well.
