Rugged Ridge manual locking hubs are crafted from impact-resistant nodular iron and feature a corrosion-resistant die-cast aluminum cap. They provide better 4WD performance when locked, and improved fuel economy in 2WD when unlocked, than automatic hubs. These hubs don't have the slippage or partial engagement/disengagement issues that plague automatic hubs. They're durable, easy to install, and cost-effective!
