Its the only knuckle kit that I've found that doesn't increase track width. Same thing for their 6" kit, no increase in track width, I'm just leaning towards the 4" kit right now. So that's the thing, all of these suspension companies say you can't use OEM wheels but if you check out the "Stock wheels on lifted trucks!" forum, you'll see tons of trucks with knuckle lifts and stock wheels. I'm just trying to find someone that specifically uses stock wheels with the Fabtech kit, haven't seen that exact combo yet. But there are tons of trucks running zone, bds, rancho, superlift, ect with stock wheels. Usually no spacers, in the front too. Which for me is the lure of the fabtech kit, if I could run it with no spacers up front I would be doing great
