Listen to folks here, that suggest RESEARCH and taking your time!
Using myself as an example:
1. I got a 2-inch spacer lift, now after a few trips to the Mtn's I wish I had a bigger lift. (the 2" lift did NOT affect ride quality)
2. I got the Rampage Recovery Bumpers (F&R)
a. Damn good quality at 3/16-in thick steel plate
b. Now I wish I had the rear-bumper with the built-in tire carrier, so as to take the weight off the new larger tires off the tail gate.
So take you time
