Different Tire Size recommendations w/ same size lifts?

Lately I have been debating getting a bigger lift, or just trying to cram bigger tires under my current Fabtech 6" lift. While doing research on the 8-10" lifts I have noticed that every company has different recommendations for their 6 and 8" lifts. With 6" lifts Superlift =37x13.5, Fabtech =35x13.5, Rize =37's, Pro Comp =35x12.5. I understand that back spacing on your wheel can make a difference, but if 37" will fit under every 6" lift why wouldn't that company tell people that? Im sure Fabtech has lost sales to superlift or Rize because people want 37's and they say it will not fit on their lift. Isnt a 6" lift a 6" lift? What gives?

I don't know specifics but I know a lot of companies will call a kit a 6" kit but it really only gives you 5 1/4" of lift etc. Similar to how some 35" tires only measure 33.5" in diameter and some 35" tires measure 34.5", does that make sense?

Most companies measure from the hub height to the fender (front wheels). Typically a 6" lift is... 6" of lift. Depending on the configuration of the front link (ours is a radius arm), the tires may hit the front bumper a little, a lot, or not at all with 37" tires. So it's not so much of a height issue as it is a clearance issue with the bumper. Most 6" lifts could probably fit 39"+ if you trim the bumper.

Also, you've got to think they're just trying to cover themselves if for some reason it doesn't lift a certain persons truck the same, and that particular truck can't clear the 37s. I know when I was looking at lifts the Fabtech for my truck showed a picture on 35s that looked like there was easily room for 38s....

I would guess that I can fit 37's, especially with the replacement bumper. But it looks really close to fender wheel on cab side when tires turned, and I rub the radius arm with 35x13.5 but Im sure that could be fixed with different backspacing.

I couldn't imagine that it wouldn't fit. I know my 7'' looks like I could run a 39'' with the factory bumpers. I know the 08s are different in the front wheel well, but the 35s my buddy has on his 5'' lift on an 05 looks small and a 37'' would be much better...
