Yukon Grizzly Locker YGLGM11.5-30: Unmatched Performance for Your Heavy-Duty Truck
If you're looking to take your off-road adventures to the next level, the Yukon Grizzly Locker YGLGM11.5-30 is the go-to differential for serious truck owners. Designed specifically for GM and Chrysler 11.5" axles with 30 spline shafts, this mechanical positive-locking differential is built to handle the toughest terrains, whether you're rock crawling, trail running, or even drag racing.
Why Choose the Yukon Grizzly Locker?
The Grizzly Locker isn’t just any differential; it's a robust piece of engineering that delivers 100% power to both tires while allowing for smooth disengagement during turns. This means you get maximum traction when you need it most, without compromising your handling on the road. The patented design includes innovative features that set it apart from the competition, like:
- Enhanced Strength: The inner clutch teeth have a larger radius at the base, providing up to 350% greater strength compared to traditional back-cut designs. This means fewer failures and more reliable performance.
- Durable Internals: Constructed with 8620 steel, the internals are designed to withstand the rigors of off-road driving, resisting breakage from shock-loading or catastrophic axle failure.
- Assembled in the USA: Quality craftsmanship you can trust.

- Axle Shaft Spline Quantity: 30
- Cover Bolt Quantity: 14

- Type: Locking
