I was gonna post as per Dean about the sliders... please dont tell me you think you can use those running boards like rock sliders...
As for the lift - and concerns - I have the 2" AC lift, which was closer to 3" in the beginning, it's been almost 2 years now, and it's sagged in the front, but a steel bumper and winch helped gravity...
CV angles, it is said that yes, the higher lift will cause more wear, although I ran over a year without the warn hubs with no issues, and have a buddy up here who ran the AC lift for 3+ years (I dont recall for sure how long) and had no issues... he has since had to replace the CVs, but he wheels the hell out of his truck, and I'm not sure how much day to day work it gets... yeah it's an issue, but I dont really think its a huge issue...
Michigan Ave mentioned topping out - yup, had the same issue, the sag has helped with that, but the only time I noticed it was when going over speed bumps, and I dont really do that all that often, when I do, I slow down, and have no issues (isnt that why the speed bumps are there anyway??)
The choice really is yours... just sharing my info.
