This is a 3" with 37x13.5x18 +20 (I believe)

I've had to trim the rear edge of the fender flare, front plastic wheel liner fold over and slight hammer back the pinch weld as well as tie back the plastic wheel liner a little bit..BUT I still need short arms at least to clear these tires and I expect some lite air dam trimming too...

yours are +20? im looking to go -44 so they stick out farther from the truck. im pretty sure i will clear my long arms with these. would like to know if my bumper will be in the way and how much inner fender will i have to cut etc..

 

I assume you are talking about 12 inch wide wheels. I have 35x12.50's on 22x12's with -44 mm offset and a 5 inch lift and I have room to spare. I wanted 37's but was afraid they would rub because of going up to a 12 inch wide wheel, but now I wish we had. I had already reshaped my inner fender liners and spaced my front bumper out about 5/8". I think you can fit them with some minor trimming of plastic and maybe the front pinch weld.

 

Mine had the same 37/13.50/22 with a 8" lift before moving to 10 1/2" and there is quite a bit of trimming he had to do.

 

Also put 22x12 -44 on a friends 4th gen with a 5" lift and had to cut a crap load and use a hammer

 

right on, thanks for the info. i appreciate the help! i assume youd have to trim a lot more than i would with the 3rd gen, i think they have smaller wheel wells?

 

No the Gen3 has much smaller wheel openings

Had to do some slight trimming to the bottom of both front fender flares.
