Yukon Hardcore Diff Covers: A Fortress of Tough Nodular Iron

Upgrade Your Diff Cover and Avoid Costly Repairs

Yukon Hardcore Diff Covers are designed to protect lockers, gears, and axles from the abuse that makes wheeling an adventure. Yukon covers are constructed from thick-walled, high-strength ductile nodular iron to endure the most severe impacts Mother Nature can dish out. They also increase the structural rigidity of the differential, reducing deflection under high-torque situations that can put severe loads on internal parts.

Whether you’re deep into a high-angle rock crawl, pulling rope and winching, or running hard on the track, aftermarket bumpers, skid plates, and rocker guards all play a critical role in keeping vital underbelly components safe. But what about your diff? It’s the lowest hanging fruit and very susceptible to damage. Crack or break a diff cover and you’re done for the day.

Stock differential covers can be overwhelmed when the going gets tough. Stamped-steel construction makes them prone to failure. Dent damage can cause interference with ring and pinion gears and spider gears, which will bring your day to a grinding halt. Another failure is cracking. Cracks let gear oil out and allow water, mud, and debris in. Both scenarios will end your fun and lead to large repair bills.

Heat dissipation is also a function of a cover’s structural design. Yukon engineers contour the inner surfaces of the cover to circulate oil more rapidly throughout the housing, allowing for faster cooling. This reduces friction, heat, and wear.

High-quality magnetic drain plugs allow for quick maintenance, and select models feature twin fill plugs to maximize oil capacity.
