There are people who have a 2" level running 33x12.5x18 with no rubbing.

 

yeah this isnt true, especially those with 4x4. I ran a 33x12.5 with 0 offset and no rubbing.

 

13 gen? I recall reading from a few people who had issues with 12.5 wide rubbing when turning with a + offset. Now there are soo many variables here like ACTUAL tire width, and wheel width, etc. but I feel its safe to say he runs a chance of rubbing.

 

I dont know the generations, but my truck is a 2015 as per my signature. I did spread my crash bars, but they wouldnt have rubbed on them if I didnt. Had a bit of space.

Now I ran 35s on my 2wd 2011 with coilovers... so on those trucks its MUCH different.

 

Yeah 2015 is 13gen. Hmm interesting, OP go for it if you'd like. I was basing my comment off of what I have read around so my experience isn't even with 13gen lol. Me personally I wouldn't chance it, takes too long cost money to get these things mounted and balanced just to find out they are rubbing (plus I don't like that short fat tire look).

 

I am still deciding between 2" fronts or 2.5" front with 1" rear block. I have read some where on this forum that 2.5" levels would cause more damage due to the angles than 2". Would this be accurate?

 

So this is a loaded question. Leveling kits dont guarantee damage, but every fraction of an inch higher you go with the leveling kit will exponentially increase the potential for damage. It all comes down to modifying the geometry and parts moving differently and at different angles from what they were designed to do. God I really wish somebody with animation skills would make something to explain this, would be such a great teaching tool showing how a spacer can cause increased pressure in certain areas and move the travel and length of travel for others.
