Are you in the market for a new vehicle and looking at the different types of differentials available? The G80 locker and limited slip are two of the most popular options on the market. While both have their benefits, there are some significant differences that can make one more suitable for your needs than the other. In this article, we’ll take a closer look at the G80 Locker vs Limited Slip, compare their key features, and help you determine which one is right for you.

The G80 Locker
The G80 locker, also known as a locking differential, is a type of differential that provides equal torque to both wheels when one loses traction. It uses a mechanical locking mechanism to ensure that both wheels receive the same amount of torque, which allows for better traction and stability. The G80 locker is commonly found on trucks and SUVs that are designed for off-road use, as well as some high-performance vehicles.
Key Features of the G80 Locker
Here are some key features of the G80 Locker:
Automatic engagement: The G80 Locker is an automatic locking differential system that engages when it senses a difference in wheel speed between the left and right rear wheels. This helps to improve traction and stability on slippery or uneven surfaces.
Electronic control module: The G80 Locker is controlled by an electronic module that monitors the vehicle’s speed, acceleration, and other factors to determine when the differential should engage. The module can also detect when the vehicle is in a low-traction situation and adjust the locking force accordingly.
Heavy-duty construction: The G80 Locker is designed to withstand the rigors of off-road use and heavy towing. It features heavy-duty internal components and a robust housing that can handle high torque loads.
Limited-slip functionality: In addition to its locking capabilities, the G80 Locker also functions as a limited-slip differential under normal driving conditions. This helps to distribute power evenly between the left and right wheels for better handling and traction.
Available on select models: The G80 Locker is not available on all vehicles, but it can be found on certain models of Chevrolet, GMC, and Cadillac trucks and SUVs. If you are interested in purchasing a vehicle with a G80 Locker, you should check with the manufacturer to see which models offer this feature.
Pros
- Provides maximum traction and stability in off-road and high-performance situations.
- Automatically engages when needed.
- Simple and reliable design.
Cons
- Can cause significant tire wear and tear when used on paved roads.
- Can be jarring when engaging or disengaging.
- Can increase vehicle weight and reduce fuel efficiency.
The Limited Slip
The limited slip differential, also known as an LSD, is a type of differential that sends power to the wheel with the most traction. Unlike the G80 locker, the limited slip does not lock the wheels together but instead uses clutches to transfer power to the wheel with the most traction. The limited slip is commonly found on sports cars and other performance vehicles.
Key Features of the Limited Slip
Here are some key features of a limited-slip differential:
Improved traction: One of the primary features of a limited-slip differential is improved traction. It helps to distribute torque evenly between the wheels, even if one wheel has less grip than the other.
Better handling: By distributing power evenly between the wheels, a limited-slip differential can help improve handling and stability, particularly in corners.
Differential lockup: Unlike an open differential that allows one wheel to spin freely, a limited-slip differential will engage both wheels to varying degrees when one wheel begins to slip. This lockup feature helps to prevent one wheel from spinning excessively and losing traction.
Friction-based: Most limited-slip differentials use a friction-based mechanism to engage both wheels when one starts to slip. This can come in the form of clutch plates or a viscous coupling.
Available on a variety of vehicles: Limited-slip differentials are available on a wide range of vehicles, from sports cars to trucks and SUVs. They can come as a standard feature or as an optional upgrade.
Pros
- Provides improved traction and stability in slippery conditions.
- Can be used on paved roads without significant tire wear and tear.
- Does not increase vehicle weight or reduce fuel efficiency.
Cons
- Not as effective as the G80 locker in extreme off-road situations.
- Requires regular maintenance and adjustment to function properly.
- Can be more expensive to repair or replace if damaged.

G80 Locker vs Limited Slip: Which One Is Best?
If you regularly drive in extreme off-road situations or require maximum traction and stability, the G80 locker is likely the best choice. However, if you primarily drive on paved roads and want improved traction and stability in slippery conditions, the limited slip is likely the better option.
Frequently Asked Questions
Here are some FAQs about the G80 locker and limited slip –
Q: Does the G80 locker cause significant tire wear and tear?
A: Yes, the G80 locker can cause significant tire wear and tear when used on paved roads.
Q: Does the limited slip increase vehicle weight or reduce fuel efficiency?
A: No, the limited slip does not increase vehicle weight or reduce fuel efficiency.
Q: Which differential is easier to engage and disengage, the G80 locker or limited slip?
A: The limited slip is generally smoother and easier to engage and disengage, while the G80 locker can be jarring when engaging or disengaging.
Conclusion
If you require maximum traction and stability in extreme off-road situations, the G80 locker is likely the better choice. However, if you primarily drive on paved roads and want improved traction and stability in slippery conditions, the limited slip is likely the better option. By understanding the G80 Locker vs Limited Slip differences the key features and the pros and cons of each type of differential, you can make an informed decision and choose the one that best fits your needs.
