not sure about those but

a 2'' leveler wont void your warranty and you can fit 33'' tall tires depending on backspacing and offset of rims! should be no problem

 

Since the stock size on a 2008 are on 18" rims you are fine. No issues.

 

Thanks guys.
So those tires will fit with no problems? (they are only 4/10'' taller and 4/10'' wider)
And a leveling kit won't void my warranty?

 

I have a PRG minilift and no it won't void your warranty no matter what some idiot dealership tech may state. Some dealerships install kits that are way bigger...

Voiding a warranty would entail improper installation and damage that resulted from such installation. Pretty hard to do with a 1 1/2 inch spacer...

 

Thanks Kronos, I did not know that.
How is the ride quality (stiffness) with the mini lift? I have been looking into the 1.5'' leveling kit.

 

since your 4wd you might want a 2'' leveler depending on if you want it to be closer to level! and you can always add more lift after the leveling kit.
