What is a cross pin shaft used for in a differential?

The cross pin shaft is a crucial component in open and limited-slip differentials. It serves as the pivot point for the spider gears, allowing them to rotate and distribute power to the wheels as needed. In a locked differential like the Spartan Locker, it ensures the spider gears are held in place for 100% traction.

Does this cross pin shaft come with new spider gears?

No, this part is a replacement cross pin shaft only. It is designed to work with your existing spider gears, whether they are from a standard open differential or a Yukon Spartan Locker.

What is the outside diameter of this cross pin shaft?

This Yukon Gear & Axle replacement cross pin shaft measures .748 inches in outside diameter. This is a standard size for many Dana 44 differentials and is critical for proper fitment.
