I replaced my OEM boots, I have to assume the originals at 120k miles, no tears. I did it while I had it all apart for the locker install in Jan10.

The mecatechs are that weird sticky rubber, where as the OEMs are a stiffer smooth rubber. Hard to explain, but for those that have handled them, you know what I mean.

I am back at factory height now, it handles offroad far better, and I fit 34s at that height with some pounding and cutting.

Good luck Bart, if you aren't lifted that high, you probably will have no problems!
