I have a 2003 4.7 2wd. I just bought some aluminum ebay coil spacers 2.5" for the front and some used 35x12.5x17 mud grapplers to go with it on stock 17's. My friends are telling me that a 2.5" coil spacer will wear out my ball joints very fast and I just put brand new moog upper and lower ball joints and control arms a couple months ago so I don't want to wear them out. Does anyone have experience or knowledge on this? I really want a leveled truck, maybe 33x12.5's would fit better with a 2" coil spacer? Any and all suggestions will be greatly appreciated!
