The original 4WD locking hub on certain Ford and Lincoln SUVs and pickups often fails due to the brittle sintered shift dial breaking, or the rubber diaphragm dry-rotting over time. This OE FIX solution features a reinforced shift dial that is 40 percent stronger than the factory design, as well as an improved diaphragm made of HNBR rubber with anti-ozone, anti-oxidation and UV-resistant additives to help prevent future failures.
- Improved design - this 4WD locking hub has a reinforced shift dial that can withstand 40 percent more torque force than the factory design to help prevent it from breaking in the future
- Upgraded materials - features an improved diaphragm made of HNBR rubber with anti-ozone, anti-oxidation and UV-resistant additives for greater durability
- Rigorously tested - this design has undergone more than 15 performance tests, including tests for salt spray corrosion, extreme cold durability, thermal cycling, and vacuum durability
- Quality assured - backed by a team of product experts in the United States and more than a century of automotive experience
