This kit uses a Dana 80 spool with conversion parts to make it work in the Dana 70. It uses your stock 70 ring gear, and ring gear bolts. In the kit there are 12 ring gear bolt spacers, 35 spline spool, carrier bearing spacers depending on which model 70 that you have, and carrier shims.This is the Dana 70 HD version but can be installed in a Dana 70U and regular dana 70.
If your looking to upgrade shafts we have you covered with our custom double splined 300m or 4340 chromoly shafts and flanges.
