Yukon Gear & Axle Differential

About Yukon Gear & Axle

Yukon Gear & Axle has built its reputation on a straightforward premise: that superior materials, advanced manufacturing techniques, and obsessive quality control produce unrivaled drivetrain performance. Headquartered in Everett, Washington, and operating manufacturing and distribution facilities since 2001, Yukon has grown into one of the most trusted names in the aftermarket drivetrain industry — sought after by off-road enthusiasts, diesel truck builders, circle track racers, and street performance drivers alike.

At the heart of Yukon's process is an in-house engineering team that uses cutting-edge design software to develop every product before partnering with world-class OEM manufacturers for production. But Yukon doesn't stop at design. Their quality labs employ sophisticated equipment — including Coordinate Measuring Machines accurate to 0.005mm, spectrometers to verify alloy composition, and Gleason Ring & Pinion Roll Stands for contact pattern verification — ensuring that every part meets exacting standards before it ever reaches a driveway or trail.

A Full Drivetrain Ecosystem

Yukon's product lineup is built around the complete drivetrain. Their differential ring and pinion sets are engineered for high-torque, high-demand applications, made with deep heat-treating and precision surface finishing for quiet, durable operation whether you're re-gearing after a tire lift or chasing faster track times. Paired with complete differentials — including the popular Dura Grip limited slip and Grizzly Locker lines — Yukon offers traction solutions for everything from daily-driven trucks to hardcore rock crawlers.

When it comes to rebuilding or upgrading your axle housing, Yukon's differential rebuild kits include premium-grade bearings, seals, and fasteners so installers have everything needed for a reliable, complete job. Their axle shafts, crafted from high-strength 1541H alloy and 4340 chromoly steel, are built to handle bigger tires and heavier loads without sacrificing longevity. Rounding out the lineup, Yukon's locking hubs — including the Hardcore Premium Locking Hub series — make it easy to switch between two-wheel and four-wheel drive while also reducing drivetrain wear during on-road driving.

The Yukon Family of Brands

The Yukon brand portfolio spans several specialized sub-lines, including Yukon Hardcore Axles, Yukon Grizzly Locker, Yukon Zip Locker, Yukon Dura Grip, Yukon Mighty Seal, and Yukon Bear Trac — each engineered for a specific performance application. With over 22 registered trademarks and associations with NHRA, NASCAR, and the United 4 Wheel Drive Association, Yukon's reach extends across virtually every form of performance and recreational driving.

Yukon also backs its products with the Yukon Extended Service Plan (Y.E.S. Plan), a no-questions-asked, one-time replacement warranty that reflects the brand's confidence in its own manufacturing standards. Whether you're a professional installer or a weekend warrior tackling your first gear swap, Yukon Gear & Axle delivers the parts and support to get the job done right.
