01 durango, changing over to 9.25 from the 03 (for rear disk) rear. Im going to go with 4.11 gears what do you recommend for differentials: front, rear, or both? Now I changed over to the NV233 tcase so its 4wd p/t. I live in ny so I do still need some drivability in the snow anyone have links or part numbers to go for?
