so ive installed the key and block kit (1'' to 3'') didnt tighten the torsion bars all the way down and going to be getting a 2'' body lift and was wanting to try to fit 35''s on but wanting new wheels to go with it but the whole backspacing and offset really confuse me lol.

im looking for something in that area but im not completely sure

 

Back spacing and offset is the same thing. A negative offset gives you more space between your rim and frame, also makes your tires stick out from under your truck. A positive offset does the opposite. It pulls your tires under the truck more and makes sharp turn hard. Putting bigger tires on, you'll need more negative offset........find rims with a zero or negative offset if your going with 35's. You also might wanna look into wheel spacers depending on the offset and how wide the rims are.

 

ok any cons to wheel spacers? and with a leveling kit and 2'' body lift would i need to do any trimming to fit 35''s?

 

Wheels spacers are harder on your ball joints. running 35's might be to big. Probably have to trim corners

 

You're much better off getting the right wheels, rather than spacers. Spacers aren't terrible, but they give you an extra potential failure point that's difficult to monitor.

4" of lift will not be enough to run 35s without rubbing (a lot). Usually, with a leveling kit and a 3" body lift, you can run 33s, but that's about it.

 

Oh well I was going by crazy4x4 guide on tire size etc but I figured I would be trimming just didn't know how much

 

It really depends on what you want to do with it. You'll be able to drive it, but the tires will rub the fenders if you hit a bump while turning. You also might want to think about what a dog it's going to be with stock gears and 35" tires.
