Gear carriers?

[XTrmXJ]

I have a 98 cherokee and I am ordering 4.56 gears.. I have a 30, and a 8.25 and was wandering if I need a new carrier for the 30 or the 8.25 any advise would be great...

The 8.25 breaks at 2.56 and up so you're okay.
The D30 break is 3.54+down, and 3.73+up so you'll need a new carrier
