Yukon Hardcore Diff Covers are constructed from thick-walled, high-strength nodular steel to protect lockers, gears and axles from the most extreme hits in off road driving. They also increase the structural rigidity of the differential, reducing deflection under high-torque situations that can put severe loads on vital internal parts. Yukon Hardcore Diff Covers feature a durable powder coat finish and high strength steel fasteners for easy bolt-on installation. It’s no secret that the underside of your rig can take a beating. Remember your diff! It’s the lowest hanging fruit and very susceptible to damage… crack or break it and you’re done for the day. Upgrade to a Yukon Hardcore Diff Cover and enjoy more peace of mind on the trail. Yukon Gear & Axle® provides the highest quality aftermarket drivetrain parts in the industry.
