what is the widest tires that will fit i found some 33-13.5-15 (if not how much triming)

 

How much lift? I hope you have lift keys on your torsion bars that are maxxed to the bump stops and a 2 inch body lift. A 1350 is a wide tire for these trucks. If you have the stock rims, I'm going say even with the truck lifted as high as you can get the crappy IFS, they won't fit. If you get a wider rim with a lower backspacing they might clear. Besides, a 1350 is a lot to ask of a 15x6 or 15x7 inch rim.

 

iam going to have lift key v8 bars and 10'' rims and 33/4 back space if not will 34=1050 work with this lift these would be on 8'' w/4 back

 

o and a 2'' body

 

Providing all the info at the first post is best! With the re-indexed keys the V8 bars are unnecessary.

 

so science i have the v8 bars i dont need the keys rite and either tire will fit
witch would you use n da mud

 

The V8 bars alone will not give you as much as a re-indexed key will. Since you got them then its okay.
