About Yukon Gear & Axle

Yukon Gear & Axle is the off-road and truck differential expert — gear sets, lockers, axle shafts, and complete axle assemblies for Dana 30, Dana 44, Dana 60, and modern AAM axles. The trusted source for rock-crawler and overland gear changes.

Yukon Gear Hardcore Locking Hub Set

Conquer any terrain with the Yukon Gear Hardcore Locking Hub Set, engineered for extreme durability and reliable performance. These heavy-duty hubs are constructed with all-steel components, including robust Chrome-Moly internals, ensuring they can withstand the most demanding off-road conditions. Unlike lesser hubs, the Yukon Hardcore series is designed to resist disengagement even under high torque applications, defaulting to a locked position for unwavering traction when you need it most.

Effortless Engagement & Superior Design

Experience quick and easy transitions between two-wheel and four-wheel drive. Engagement is achieved with a simple 1/3 turn of the low-profile, all-steel bezel. This design not only offers convenience but also minimizes the risk of snagging on obstacles during aggressive off-roading. The hubs feature a proprietary coating on the locking gears, which reduces friction and significantly extends their service life.

  • All-steel construction for maximum strength
  • Chrome-Moly internals for extreme durability
  • Resists disengagement under high torque
  • Easy 1/3 turn engagement with low-profile bezel
  • Proprietary gear coating for reduced friction and extended life
  • Limited Lifetime Warranty against manufacturer's defects

These Yukon Hardcore locking hubs are a direct upgrade for select GM 8.5-inch front axles and Dana 44 axles with 19-spline configurations. They are specifically designed to fit a range of Ford Bronco, Chevrolet, and GMC trucks and SUVs from 1971 to 1981, providing a perfect fit and enhanced capability.
