Does anyone know what rearends in 2500?

Does anyone know for sure what rear ends are in the 03 2500 Diesel as far as the name and size of them (front and rear)

I thought that the 99 2500 I owned before had a Dana 60 up front and a Dana 80 in the rear but I'm not sure if the new 03's have the same pumpkins in them or not.

I'm wanting to buy a set of gears and polished or aluminum covers for both ends but I'm not sure exactly what rearends are in them or what, if any options or different choices are availible.

I have the 373 gears now with the stock 265 tires but I'm going to the 315's and would like to go to lower gears too.

Anyone know where to get a good price on gears and about what size I should go with as far as ratio?

Thanks for any info. :smokin:

should tell you up under the hood on your detail sticker
