This ARP bolt kit will replace all of the bolts for the retention plate inside of the transmission. This is the plate that holds the pinion on to the transmission. They are made from 8740 chromoly so they have superior strength over stock.
This bolt kit will save you from having expensive repairs to your transmission since the factory bolts have an extremely high tendency to wear out or fail do to the high stress or the bolts being over tightened or even shearing in half.
