Detroit vs. Grizzly Locker: An In-Depth Comparison
Detroit Lockers and Grizzly Lockers are both popular brands in the aftermarket differential locker industry, offering solutions to improve off-road traction. They provide alternatives to open differentials, which can leave a vehicle stuck when one wheel loses traction. But what exactly are the differences between these brands and which might be better suited for your needs?
Detroit Locker Explained
The Detroit Locker, a product of Eaton Performance, is a type of automatic, or “no-spin,” locker. This means it mechanically locks the axles together until torque is applied, forcing both wheels to turn at the same speed. This provides maximum traction in challenging off-road conditions, as it ensures power is always delivered to both wheels regardless of individual wheel slippage.

Advantages of Detroit Lockers:
- Maximum Traction: Provides superior traction compared to open or limited-slip differentials.
- Durability: Known for their robust construction and ability to withstand harsh conditions.
- Automatic Operation: Engages and disengages automatically, requiring no driver input.
Disadvantages of Detroit Lockers:
- On-Road Behavior: Can exhibit harsh engagement and disengagement, leading to unpredictable handling, especially on paved roads. This can include “clicking” or “clunking” noises during turns.
- Not Ideal for Daily Drivers: Due to the on-road handling characteristics, they’re generally not recommended for vehicles primarily used for daily commuting.
Grizzly Locker Explained
Grizzly Lockers, manufactured by Yukon Gear & Axle, are also automatic lockers designed to provide enhanced off-road traction. They function similarly to Detroit Lockers, mechanically locking the axles together to ensure both wheels receive power. Grizzly Lockers are often seen as a cost-effective alternative to Detroit Lockers, while still offering significant performance gains.
Advantages of Grizzly Lockers:
- Improved Traction: Offers significant traction improvement over open differentials.
- Cost-Effective: Generally priced lower than Detroit Lockers.
- Durable: Built to withstand off-road use.
Disadvantages of Grizzly Lockers:
- On-Road Behavior: Shares similar on-road handling characteristics with Detroit Lockers, potentially causing unpredictable handling and noise.
- Potentially Lower Longevity: While durable, some users may report slightly shorter lifespans compared to Detroit Lockers in extremely demanding applications.
Detroit vs. Grizzly: Key Differences
While both lockers serve a similar purpose, the main differences often come down to brand reputation, price, and perceived durability. Detroit Lockers are often seen as the “gold standard” due to Eaton’s long history and reputation for quality. Grizzly Lockers aim to provide similar performance at a more accessible price point.
