A factory thin ring gear was used on 1955-1956 carriers with ribs on the back of the ring gear side. The 1955-1956 open dropout casting numbers end with 306in. A new ring and pinion or ring gear spacer is required when replacing the factory 4 series case.

The use of synthetic oil is not recommended and may result in aggressive or noisy operation.
