No; 33x12.5. Any wider and you'd have to lift.
With the 37's, I'm assuming you have a 6-inch lift. Google 33x13.5x20 and you'll see some NICE setups, but they're all lifted. It's the width that's the issue, not the height. Even on the 05+ trucks, you can't get enough offset on wheels to get them tucked back in under the fenders; well, at least without spending $1000 each... (you can solve problems like these if you throw massive amounts of money at them.)
The spray trail from the front wheels center-punches the mirrors, and the airstream around the mirrors wraps the water around onto the glass. That's going down the road in a straight line. When turning, if you're at speed, you're not going fast enough to throw the water out any differently. At slow speeds, the water doesn't get thrown far enough to hit the mirrors, and doesn't even really wrap up onto the hood.
The weight of the ranch-hand brings the height back "down" to stock height, with the heavy-service suspension package. The heavy service suspension more or less equates to a 2-inch level.

Oops I completely misread your post I read that you had the equivalent to 33x13.5 haha that could be an issue. Do you know how much of a lift is required for the 13.5? Yea i currently have a 6 inch lift but like i mentioned before the ride is very rough and simply i like that "stuffed" looked better than the lift. Not only that but when going down the highway and the wind is blowing..... let's just say that truck tends to catch some of it. And idk if you been in NM but our roads aren't anything to be proud of.

With the 325/60/20's, I would have needed to cut some serious gouges in the fender, so I can't imagine any less than 4 inches. I think the general recommendation around here is that that size tire needs a 6-inch lift. The problem is that most companies that build lifts don't go any smaller than 6 inches, preferring to "level" for anything less than 6. This, of course, looks stupid, especially when doing that idiotic "california rake" garbage.
I may try 2 inches next time around, using the factory 350 blocks and a 2-inch "levelling" coil from one of the big-name lift people.
Since you already have the lift, you might investigate replacement springs for the lift. I think ICON and Fabtech (are those still legitimate names?) make replacement springs.
As for the roads, unfortunately I'm all to familiar with them. You might try changing your tire pressures to soften up that ride a little.
I finally came to the conclusion that where I was driving was more the problem than any inherent problems with the suspension. Mine rides nicely on the freeway, but where I was living up till a month ago, they couldn't make a smooth street if you paid them overtime.

Haha yea these roads will give a beating even when i w as on the freeway tho it was still hella rough. And as for the tire pressure I'm already 15lbs under any lower than that and i might as well replace them with pillows.
Well let me ask you this my rims are 20x10 33x12.5 fit on them.(i just searched this so i have now decided to go with 12.5 instead of the 13.5) Do you think they would rub stock height? Or am just going to have to sell everything and get new rims as well. ( not really what i want to do.) Bottom line i want to return to stock height and still keep my rims.

If you want the wide tires, you HAVE to keep the rims. They're harder to find than the tires.
Mine are 20x10. I actually wanted 18x10, but they were too hard to find. I wanted the 325x60x18 tire size. It's the same diameter, but the rubber itself is taller, and about 3/4 an inch wider tread patch. I had to go with the 305x55x20.
In an E-load-range tire, IMHO, anything less than a 60 aspect ratio is going to give unacceptable ride quality. The sidewalls are simply too short to be able to flex properly over pavement chatter. My tires are 55 aspect ratio, so their performance on rough pavement is less-than-desirable.
Note that when you're running "that close to the edge," the same numerical size tire from different manufacturers will vary slightly on whether or not they rub. It depends on how closely they stick to the nominal size when designing the tread pattern. Mine are Nitto Terra Grapplers, and I get the impression that they push the nominal size as far as they can go. A BFG would probably not rub, IF you could find one.

Well this is good to know. Now I am 99% sure of what i want to do.... Unless something pops up between now and then. But I would rather have the stock height again simply for the fact that this truck is my going out truck, and well lets just say when the only place to park is a parking garage 90% of the time my truck doesn't fit in one. Gets kind of annoying having to park so far away. So it is set back to stock height with the 20x10 rims and 33x12.5 rubber to go with it....... Any suggestions that might be of good importance. Like good aftermarket coils or such? In all honestly I am more concerned for the front end then the back ( it only has blocks on it)

Hate to break it to ya, but even after dumping the lift, you're probably not going to be able to get into a parking garage. MAYBE with going back to stock height tires (31 or less). I gave up on garages after putting on a mag-mount CB antenna, on stock tires. Garages just aren't built for these trucks.
I haven't researched coils, since no one makes stock-height coils except Ford. My problem isn't trying to get into garages, it's trying to get into the TRUCK.

Well the garages I've been close to I'm only over by a couple inches.... And as far as getting in this bad boy that's a piece of cake for me 
not like i use them often but its mainly when me and the gf are all dressed up that i like to get a close parking and well kind of difficult with height restrictions in some places. But now I am looking forward in getting this rig down to stock height. 
thanks for all your info friend this really helped me out a whole ton.
