Well aware of the axle wrap that can occur with blocks. But which would be a better choice. 2" block or shackle? I am only running 31s now so fender contact would not be a problem with the shackle. Do shackles cause any unwanted problems like blocks do?

 

shackles move your axle forward i believe. i've heard horror stories about off roading and blocks, but that is only guys who double up on a block or under extreme conditions. i also didn't want the axle closer to the bedside so i went with a AAL.

might be something you wanna consider or look at.

btw, make a signature so we know what your truck is equipped with.

 

Aal or new leafs

 

never had a problem with my blocks. gota remember, the 4x4 comes with blocks

 

In your situation, it should make no difference which one you choose.

 

I'd go with shackles, but either would work.

 

I would imagine if your buying everything new shackles would be cheaper (belltech 6400's are 50-60 bucks) rather than buying blocks and new u bolts. Shackles will give you a little more flex too. Blocks may be a little less work if your leaf bushings are seized, but I'd recommend shackles over blocks any day.

 

I am curenntly running 4" leafs in the rear, but need I a little boost but am undecided using the blocks or shackles. I ran aal still they sagged.
