Product Information

YUKON GEAR DURA GRIP LIMITED SLIP DIFFERENTIAL LOCKERS

Yukon Gear’s forged steel and composite Dura Grip lockers give you back that power you lost when you installed those oversized tires, which means more traction on the trail – a must under extreme or dangerous off-road conditions. Yukon Gear was founded in Washington state – where extreme weather and off-roading are commonplace – and manufactures performance products that were built to perform and built to last in harsh environments.

  • Transfers torque to the ground for the best traction
  • Features forged steel internal components and nodular transfer case
  • Upgrades available for racing applications
  • Offer hardcore traction with smooth engagement
  • Raybestos clutch-style positraction means optimal performance and durability
  • Locker is conveniently rebuildable which saves you money
