I own a 94 F150 XLT 2wd auto. I plan on a 6" suspension lift and 33x12.5 BF All-Terrain KO's. I was planning on a Detroit EZ Locker in the rear to aid in some non-serious, small time mudding. Is this the right set-up for what i have in mind?

 

You should be fine, I have the factory Ls on my 93, with no lift and P235/75R15's AT's. I am glad to have LS, it has saved my Butt in numerous occasions. Your setup would/will be WAY better than mine. I forcast no problems as long as you remember your truck is a 2wd.
