I've had this truck fire .5 yr now. I'd speculated and been too lazy to get down and check what size/ Manufacturer lift it has, I assumed a 4" from looking.

Aftermarket A arms by trail master, I noticed while swapping out a super busted idler arm and the tie rods. I don't know my way around a lift kit.

Question #2 : when I go back from MT I plan to put this thing on 35 x 12.5 x 15 's. Will they fit? I'm sure the height will be fine, maybe removing stock yota front bumper and even trimming if I have to. Im worried about the width. I ain't runnin spacers, and I don't wanna get tires just to figure out they rub all nutty at full lock.

 

Additionnally: those are 33's x 12.5 pictured here.

 

You definitely have a 4" bracket lift on that truck.

I believe stock IFS measures approx 19-20"" from center of the front axle to the bottom of the fender (obviously this number varies between vehicles and with age/wear).
I've got approx. 2" of lift and my truck sits at 22.5"

In regards to your tires - if you have 33x12.5 tires now, most likely the 35s will fit with some minor adjustments. I know on my truck I had to make the 33x12.5 tires fit with some firewall/pinch weld pounding as well as a trim on the bumper/valence.
What I would do is go take your truck out and try to get the front at max flex/articulation, both up and down...and while turning in both directions to the stops, and get out and observe each situation to see where you might make contact with 1" more radius added.
