do i need new carriers?

im going to regear my dana 30 and 8.25 from 3.07's. do i need new carriers for both of them? its going to be my dd, running 31's, i guess im going to go with 4.10's? so do i just need to get the r&p and master install kits??? thanks guys

You will only need a new carrier for the D30!

ask for a carrier for a 4 cyl. wrangler or cherokee, high pinion or low pinion, it does not matter. the part number is 5252590
