I agree, I wheeled IFS for years without a skid plate. They are a waste of time and a complete poser product. After I first bought my truck new I had one of those pretty aluminum northwest off road ones from the old days and it just helped me get hung up on things and eventually got destroyed beyond recognition. I did end up making a new cross member out of .25 wall 2x2 square tube for under the diff because I tore off the tabs that bolt to the IFS diff cover from the torque of 5.29s and lockers.
If it's not there it can't hit stuff!
