If you’re knee deep in mud with a failed automatic hub and a disabled vehicle, the only way to repair it is to replace it. The question is, with what? Factory automatic hubs have a history of failing when you need them most. A damaged hub will render your 4×4 useless and leave you stranded. Wish you could swap your automatic hubs to a set of manual locking hubs? Rugged Ridge has you covered. Rugged Ridge Manual Locking Hubs are unanimously recognized as the world’s toughest hubs by our thousands of satisfied customers worldwide. Brute strength matters, which is why the bodies of our hubs are crafted from impact resistant nodular iron, and feature a corrosion resistant die cast aluminum cap. Our hubs deliver better 4WD performance when locked and improved fuel economy in 2WD when unlocked, than automatic hubs.
