I take my truck camping all over the western US, been to Utah, OR, CA, AZ, NV. Sometimes drive marginal roads so was looking to beef up my truck just a little for better clearance and handling off the pavement. Also I have a hitch mount bike rack that would drag through the dips sometimes.
First I got some bigger tires (235/75/15) Goodyear Wrangler's. They fit the stock truck, but pretty much filled up the wheel wells.
I cranked the torsion nuts a bit and got about 1 3/4" of front lift out of that.
