Default zone 2" level 285/75r18 rubbing crash bar frame mount

ok so I just got a zone 2" level kit installed on my 2018 f150. I was told that with these tires, 34.8x11.3, that rubbing would not be an issue if I stuck with my stock wheels, which are 18x9. I just had some toyo open country at2's installed that are 285/75r18 "34.8x11.3" but they are rubbing bad on my rear crash bar frame mounts. I have always heard to stay away from wheel spacers and obviously bending my crash bars with a porta power will not help. I would prefer not to cut the frame mounts since my wife drives this truck most of the time. Has anyone else had this issue? how did you solve the problem?

Get smaller tires or more lift

yea I just didn't know if someone else had this same issue and could provide insight into which offset on an 18x9 would work so I could just spread my crash bars, or maybe someone that had good experience with wheel spacers. I will be running off-road since I am a pipeline construction inspector. If all else fails I will cut the frame mounts off too then weld them back on after I get more lift. I just did not want to do that if I didn't have to.

sorry I found the leveling kit thread in the 15 to 18 f150 forum so I posted over there. I finally got a chance to get some good measurements in the daylight and i plan to just cut the crash bars and their mounts at the frame. I figure a wafer disk or sawzall would work great. it's not like I cant weld it back on.

Just my .02......I know people do this all the time, but if you are in a off-set crash...you or your wife will pretty much be disabled from the tire coming into your cabin compartment. I know the chances of that happening are very very slim, but they are there for a good reason. I absolutely would not compromise the cabin compartment just for looks/whatever other reason. My brother-in-law is contemplating doing this very thing as he put super-wide tires on his 15 Lariat, but I strongly discouraged him from doing this. Don't know why someone would compromise their legs for looks. Just me I guess.

it is not for looks but more for offroad capability. the other trucks where I work run 35's so running something under that you run a good chance of high centering in the ruts. My wife drives this truck most of the time and she does not want to lift it. why are there no crash bars on the raptor or regular cab trucks? Do they have some other safety feature? Is this just an issue due to the aluminum body?

I have no clue about the raptor vs regular trucks. Automakers and engineers do a lot of things to improve safety.....some are over-the-top and some make a lot of sense. The crash-bars seem like they make a lot of sense if you look at crash videos of the off-set frontal collision. Like I said...the chances of that crash ever happening are absolutely slim to none, but if it ever would, they could save your legs.

I have been looking into this more. Since my wife is driving that truck for now I plan to leave them. I am now trying to find the proper offset for a 18x9 wheel that will move the wheel and tire out enough so the tire rubs the crash bar instead of the frame mount. Then I can just use my porta-power to get a little more room.

1) Offset matters. A lot. And if you're rubbing with a 285-series tire on a 18x9 wheel and a 2" spacer, I'm guessing you went +0, or more likely, negative. +18 would work fine.
2) Leveling spacers are for looks, not for better-off-road capability. In even moderate off-roading with a leveling spacer, you're going to be subjecting your suspension to excessive down travel because strut spacers push the whole assembly downward. They also limit up travel. Get a leveling struts/coilover (like a Bils 5100 or 6112) if you're trying to raise the front end and still want to wheel it without breaking something.

Well I plan to eventually add a 6" bds coilover lift. However my wife is driving the truck for now with me only occasionally needing it on the ROW. She does not want it lifted. The leveling kit was so I could fit taller tires to help keep me from getting high centered. They also make it easier to climb onto the mats we use in the really wet areas. My wheels are the stock 18x9 wheels that come on the xlt sport models. Does anyone know what the offset is on the stock wheels? I just find it odd since I have not heard of anyone else rubbing the frame mount for the crash bars. I was just going to cut them off but she does not want me to do that either.
