  • Q:

    What is the part number for the notched pinion cross shaft which is required when installing 4.56 gears in the 7.5" ten bolt gm rear

      I'm happy to help, Bmerc! This Motive Gear Ring and Pinion (Part No. GM7.5-456) does not have a recommended replacement cross shaft provided by Motive Gear. I was able to find another option from Richmond Gear for the 10 bolt 7.5" open differential, Part No. 80-0270-1. This is not available on AdvanceAutoParts.com, I suggest checking with your local store for availability.
