An Improved Design

Yukon Gear & Axle is proud to introduce the Grizzly Locker, the latest in locking differentials, featuring an 8620 steel alloy case, forged 8620 internals that are hand fitted for faster engagement, and a patent pending design which reduces common locker failures.

The inner clutch teeth have a larger radius at the base; offering improved strength versus back-cut designs by up to 350%. Larger teeth also help to avoid breakage against shock-loading or in the event an axle breaks.
