I have skidrow under armor front to back and I'll tell you, the stuff is beefy. I probably added 150+ pounds to my jeep between oil pan, t-case, and fuel tank skids. They proved their worth a couple weekends ago on the rubicon. Having both oilpan and t-case skids will keep you from getting hung up on your crossmember also.
So yeah, if you can get a good deal, I would go for it.
