I am looking into a sas and trying to gather up all the info i can about it. I have a 98 F150 and Im wondering if there is a straight axle front end that has the same bolt pattern as the stock rear. I know the stock is 5X135mm.

AFAIK, no. Your best bet to ditch the rear and grab an 8.8 from a 96 that has the VSS in it.
Or, you could SAS a Super duty Dana 60 and swap in a Sterling rear into the back.
Is the SAS kit worth the 2 grand they want for it. All that is included in that price is all the hardware for adapting the new gear and a 4 link kit, no springs or axle.
I don't think it is, but then again, I don't have a newer truck.. I think you'd probably be better off swapping in a leaf spring axle and doing the work yourself, or getting an offroad shop to do it.
this is the vital point in the build up where you need to sit down and ask yourself are you really gonna pound on your truck hard enough to necicitate 1 ton drivetrain. i know i would but i run 40" meats on the rocks and in the mud. haven't broken one yet thank goodness but i fear I am inching closer.
if you plan to seriously wheel your truck and you have a high possibility of flipping it or you have a fetish for the skinny pedal, i don't recommend it. it can be very expensive and time consuming
In this new of a truck, it might be worth the money to grab a kit with good instructions. This won't be like the 96 and older trucks, were frames are the same, and 1/2, 3/4, and 1 tone gear is nearly interchangable and all bolt on. Your 98 F-150 is a wishbone suspension with torrsion bars, and bears no similarity to its straight axle, 1 ton brothers. All parts are going to have to be custom made, wether in kit form or DIY. And the kits out there are for Dana 44 axles AFAIK, so you still have your 35" tire limitation. Not worth it unless your going to pound on it, which I don't see happening in that year of a truck.
why would this limit the tire size to 35s F-T? If I do decide to go this way Im not gonna go ridiculous. I need nothing more than a 1/2 ton truck. I just am not crazy about IFS with anything bigger than 33s. Im ordering 37" IROKS next month and they wont go well with the IFS either. I dont think i need any 1 ton axles so what would be the best all around combination with the 37s and 11 inches of lift? What is the purpose of the 4 link system. Would I need one for the back also?

are you planning to actually wheel this truck, or are you just mallcrawling?
if you actually wheel the truck, 35 is probably about as big as you want to go.. if you are mallcrawling 37-38s will work fine.
the purpose of the 4link is to locate the front axle under the truck. you won't need to 4link the back, since you already have leafs under it.
i have a friend who put a d60 with leaves under a ifs chevy 3/4 ton wouldn't it be possible for FAB to do that too? it wouldn't ride as well as the 4link, but it might be worthwhile in the price savings.

you will never get 11" of lift from ttb successfully. you will need to do a SAS but you can just get a good D44 and still be good to go. my question is why 11"? just trim some fenders or find other ways to get the tire under there.
a general rule of thumb for us hardcore wheelers is that if you go much bigger then 35's on 1/2 ton drivetrain you are asking to break something. I busted several axles on my 93 F150 and they were cheap radials, that's why decided to just go ahead and get an F250 and build it up...mucho strongero. so we tell ppl anything 35" and above is better left to 3/4 ton's and up unless you are just gonna crawl at your local mall!

I all ready have 9 inches of lift on now. I do not do any hardcore wheeling. Just trail ridin to get to the good beer drinkin spots and a few mud holes every now and then. This truck is more looks i guess but i still want to make it a tuff well built truck.
