Yukon Hardcore Locking Hub set for Dana 60, 30 spline. for Ford (1999-04) Yukon Hardcore Locking Hubs feature chromoly internals and all-steel construction for ultimate durability and strength. These hubs won't disengage under high torque applications and default to the locked position in use. Engagement comes from just a 1/3 turn of the all-steel, low-profile bezel, ensuring quick changes between two-wheel and four-wheel drive. Yukon Hardcore locking hubs are not only great looking, but feature a low-profile design to minimize impact with obstacles, as well as a proprietary coating on the locking gears for decreased friction and a long service life. •Fits 1999-2004 Ford Super Duty •30 spline •All steel construction •Chromoly internals for added strength •Low profile bezel to reduce impact with obstacles •Defaults to locked position •1/3 turn from disengaged to engaged Technical Notes Does NOT work with Stage-8 lock nuts.
