if i get a 2 in BL and 2 in shackle if not wat is the biggest that will fit

 

If you drive straight, and never turn you should be ok.
Honestly, If you plan on any offroad driving, you'll have to trim ALOT.
Lets see, air shocks, AAL's, T-bar crank, am I forgetting anything?

 

im doin thew tbar crank and the stuff i mentioned ... so wat size will fit and look good

 

31's in a AT

Here's a list of things Jigg did to a ZR2 Blazer, to be able to take it offroad with no rubbing issues.
On 33's.

2" BL
2.25" Lift Shackles
1" Tbar crank
Air Shocks
Add A Leafs
A bit of fender trimming

 

i fit 31"s with a tbar crank and a 2" aal. with a body lift you might be able to fit 32's but it all depends on how agresiive the tread is and how much your suspensions is sagging.

 

It also depends on rim backspacing and tire width aswell.

 

ok b/c i found a killer deal on some 33s...450 for all four mickey tompson mudd terains
