The OEM 5R110 rear ring gear hub failure has been addressed with our 4140 HTSR steel hub. Withstands the demands of high torque and heavy duty applications.

In 2003-2004 5R110 models, the Low Reverse ring gear hub had holes machined into it to cut weight in the finished unit. This proved to be a fatal flaw as these ring gears hubs broke under stock hp levels. Ford upgraded the hub to solid steel in 2005 which remedied this issue. This is a great upgrade for those rebuilding an 03-04 model or building a full billet transmission. All Dieselsite Legendary Transmissions are built with the solid steel 05 model hub.
