Not sure about this because this is just what I heard from a buddy of mine with 6in lift on his 2500

he told me that I should be able to fit 35x12.50s if I put a leveling kit on top of my 2.5in lift I have lift springs in the front and blocks in the back...

has anyone you know or have any of you guys did this?

Any help is great

 

What size are the blocks in the back?

You should be golden, might get a bit of rub on the control arms, and maybe the inner fender well, you can heat that plastic, and re-form it a bit for added clearance.

Might have troubles just installing a leveling kit though...... I think over 3" of lift, the geometry on the control arms starts getting weird....... Something you might want to investigate.

 

its a 2.5 block and 2.5 coils

 

If you only have coils in the front....no longer control arms, longer track bar, etc.

You will probrably run into geometry issues like stated, now I have not done it but there have been people that put diesel coils in and gain around 3.5"-4" in the front and never changed anything else, and said there trucks tires wore ok and it rode nice
