Armor isn't a sexy upgrade like lift and tires LOL but to many people get lift and tires with no thought to armor which is useless with out armor. This video is one of my first trips off road with just the RC lift OEM skids. I still have the stock running boards on LOL You can hear me dragging the plates on the rock. If I didn't have the skids my TC might of been shot. They were all laughing at the end because the wranglers before me had a hell of a time getting up that and I kinda just walked up.

If you can get the stuff used and save some money go for it. The only issue like I said is needing the bracket because of your fuel tank. If you get 4xG skids they make the same bracket for their skids as well to work with your fuel tank skid.
