I might be off base here but don't Edgy Mods do a similar modification without tearing up your truck?
Lifting the truck a couple inches (Edgy Mods can provide ~2.5" lift) does very little to clear larger tires, due to the shape of the fenders. The added lift will also affect ride, CV and ball joint angles, although most noticeably at max lift. You can see this by comparing tire clearance at normal and increased ride height. It is most evident behind the front tire while turned ~1/2 way.
The fender liner pull back is even less intrusive than lift links and provides more tire clearance, assuming the wheel offset is somewhat positive. The lift links help, but 35s will require fender liner mods to clear at full lock in bump, with or without lift links.
Once tires trend toward larger 35s or offset around 0, additional trimming of the liner will be required or a liner pull back and lift links combined.
Large negative offset, or tires larger than 35" (nominal) will require trimming sheet metal or much more than lift than links can provide. As far as I know, there are no larger commercially available lifts for the air ride at this time.
I purchased Edgy Mods lift links before getting my 35" (315/70R17 on +18ET) winter wheel and tire package but have not installed them pulling back the liner was enough to clear in almost all situations. I'll likely go to aggressive 35" AT or hybrid tires on 0ET for summer when the OE tires are done and will install the links if I can't get enough clearance with additional fender liner mods.
