Sure, an ifs rig will last fine with <33" all terrains on mild trails, where you don't need to spin the tires to get going anywhere. Once you put on bigger, grippy tires, get on some trails where you need those tires, the ifs isn't gonna be happy. Do I have an auto locker up front? no, all of my superlift brackets bent from the torque placed on the front diff. I mean, I do have some EB parts in the motor... but its still a 22R with stock cases and it tweaked everything multiple times.

For example: This is the drivers side front diff drop bracket. It twisted all kinds of ways on a normal NH skidder trail.

I welded the angle iron on there, took it out on another trail, and the bracket snapped right where the bracing ends - about where the bolts go through. Nothing major, no clutching at redline, just normal rock-driving. This is the trail it broke on the second time. [Linked Image]

Similar story for just about every bracket in my front end. Except for the bumpstops bending.. this is what eightyeight was referring to as a blue UFO 5ft off the ground. In reality it was 4ft. Usually truck is treated relatively nicely though..
