get a 8.8 if your going with those gears. cause im guessing your planning on some big tires and the 7.5 is not going to withstand anything bigger then 33s.

EDIT: let me rephrase for those who will jump all over me, you can get away with bigger meats on the 7.5 but i dont recommend it.

Get the 8.8 and install the 4:56's in there... it's built much stronger and will last longer.

You get what you pay for.

Not sure what engine you got but my 4 banger and 4.10's is fine with 33's. I will eventually get lower gears cause I will be getting tires. And most 8.8's have 4.10's stock. I would just get the 8.8.

You will have to flip the spring perches and weld new shock mounts on it.
