I totally agree with Huey, you should do your mods as you get comfortable with what you have.

Maybe do the shackle lift, and then go for a set of skids? I just installed my Shrock fuel tank skid tonight, and the quality is superior to the skid row in my opinion.

I started with just the PML, then upgraded to the full 3" lift. I came from a TJ with 37's so I opted for the 3"BL and 35's.

Last fall I bit the bullet and went for the SAS, so yes my truck is bigger than most of the other X's, but I wasn't trying to build a monster truck.
