I also read ill loose my factory skid plate(i know its weak and almost pointless just dont like the open space) I dont hear any noises or shakes at full lock on the wheel... Can someone help me out with this?!?!
People generally don't bother with diff drops unless they have lifted 3 inches. I don't know what setting you have the 5100s at, but 2.5 is the max for those. Anyways, the effectiveness of diff drops is strongly debated. The idea is that they would reduce the CV angle caused by the lift, which can cause the CV boots to rub and tear prematurely. But apparently they aren't effective at preventing this.
If you bash the factory skid hard, yes, eventually you will bend it up. It isn't super stout, but it is better than nothing. Then you will have an excuse to buy some real armor. Might as well wait until you prove you need it.
