Just bought my 06-lariat 4wd this past sunday and im trying to figure out what the best wheel tire combo sizes etc, and can i do the 6" suspesion lift w/o voiding my factory warranty? fabtech or pro comp? I like the wider stance look w/my tires, so keep that in mind....

 

For your lift question. You can put a lift on without voiding your warranty. When you go to the dealer for service for lets say some kindtransmission of transmission trouble they probably wont look too highly on your 33 or 35 (whatever size you plan to run) tires. They will give you some lame excuse, unless you have a good one like me. First they have to prove that the aftermarket part you put on somehow made your factory parts fail. Look up the Magnusson Moss Warranty Act. As far as rims and tires I still don't know and I have been looking since end of July when I bought the truck.

 

I'd suggest the 6 inch Fabtech lift with a 325/65-18 (35x13.00) tire on an 18x9 inch wheel with 5 or 5 1/2 inches of backspacing.

 

How much would those stick out?

 

A 9 inch wide wheel with 5 inches of backspacing will stick out 2 inches more than the OEM 7.5 inch wheels with 5 1/2 inches of backspacing on a stock truck. However, most 6 inch lifts will increase the front track width a couple of inches also.
