What gear ratio is required for the Yukon Grizzly Locker?

This Yukon Grizzly Locker is designed specifically for axles with a gear ratio of 3.92 or higher. Using it with a lower gear ratio is not recommended and may lead to improper function or damage.

Does this locker come with everything needed for installation?

The Yukon Grizzly Locker itself is included, but installation typically requires additional components such as new ring and pinion gears, bearings, seals, and installation kits. It's recommended to consult a professional mechanic for a complete parts list and proper installation.

How does the Grizzly Locker handle on-road driving?

The Grizzly Locker is a mechanical locking differential that automatically engages to provide 100% power to both wheels. While it allows for disengagement during turns, it's designed for off-road or racing use. On-road driving, especially in slippery conditions, may feel different, and it's important to drive with caution.

Product Details

If you're looking to significantly improve traction for serious off-road adventures, rock crawling, or even drag racing, the Yukon Gear Grizzly Locker is a robust mechanical locking differential designed for Dana 44 axles with 30 spline count and a gear ratio of 3.92 or higher. This locker engages automatically, sending 100% of available power to both wheels simultaneously, ensuring you maintain forward momentum even when one tire loses grip. When you're back on the pavement or navigating tight turns, it disengages to allow for normal steering and handling.

What sets the Grizzly Locker apart is its hardcore construction and patented internal design. It features 8620 internals for added strength and an advanced gear tooth design with a larger radius at the base. This unique feature offers up to 350% greater strength compared to other designs, making it much more resistant to breakage from shock loads or catastrophic axle failures. This well-built unit is assembled in the USA, reflecting a commitment to durability and performance for demanding applications.

This locker fits a wide range of vehicles, including many Chevrolet and Dodge trucks and SUVs from the 1960s through the early 2000s. It's a substantial upgrade for anyone who pushes their vehicle beyond the limits of a standard open or limited-slip differential. Keep in mind that installing a locker typically requires setting up ring and pinion gears, so it's a job best suited for experienced mechanics or a professional shop.
