I've done a good amount of stuff to my truck since I got it last month, but I wanted to get some opinions on this before I get too carried away. I've been thinking about putting a leveling kit on it, with wheel spacers and 33's. I think it'd look mean with some aggressive tread tires with the wheel spacers. What do you all think?

This is the truck as of now, windshield is getting tinted on Thursday.

 

It will definitely look better with a front level and some beefier tires.

But keep in mind with bigger tires comes added stress on the transmission which leads to regearing, your 4x4 gotta match front and rear. Unless you've already got 4.10's are something in that neighborhood.

 

If you're only concerned with looks go with it. I would recommend rims with 4" of backspacing instead of spacers though.

 

Just dont expect it to drive like a v8 powered truck... 3.55 gears and 33" tires is gonna feel more like driving a 4 banger...keep that in mind. It will be sluggish and your mpg will likely suffer a bit.....unless you change the gears to 4.10 gears offsetting the 33" tires. I have two sets of rims and ironically the ones that stick out more actually rub on my fenders more than the ones with factory backspacing.. (I have a body lift and 35" tires though)

 

You can fit 33"s with no lift, I have 35"s with a 3" coil spacer and my tire only rub at full lock, but there are adjusting bolts on your knuckles on the front end.
Just adjust those out to stop the tire from turning so far.
