A limited slip differential is a device that’s designed to distribute power evenly between the two wheels of a car, helping to improve traction and stability on the road. But does it really make that big of a difference?
In this article, we’re going to explore the benefits and drawbacks of adding a limited slip differential to your car. We’ll take a deep dive into how limited slip differentials work, what types are available, and whether or not it’s worth the investment. So sit back, grab a cup of coffee, and let’s get started!
Understanding Limited Slip Differential
When it comes to a car’s drivetrain, the differential is a crucial component that allows the wheels on each side of the vehicle to rotate at different speeds while maintaining traction. The differential enables the outer wheels to travel a greater distance than the inner wheels when taking a turn, helping the car maintain stability and control.
A limited-slip differential (LSD) is a type of differential that goes a step further in providing better traction and stability. Unlike a conventional open differential that simply directs the power to the wheel that has less resistance, LSD can send power to the wheel that has more traction, making it ideal for performance-oriented vehicles and off-road applications where maximum traction is needed.
- There are two types of limited-slip differentials: mechanical and electronic.
- Mechanical LSD uses a series of clutch plates, gears, or cones to create friction between the two wheels, preventing them from spinning at different speeds.
- Electronic LSD relies on sensors, computers, and a complex system of hydraulics to monitor wheel speeds and distribute the power accordingly.
Although LSDs are commonly associated with high-performance sports cars, they can be advantageous for any vehicle that needs better traction and stability. That includes everything from family sedans to commercial trucks.
If you’re planning to invest in a limited-slip differential, it’s important to consider your driving needs, the type of vehicle you have, and the level of performance you’re looking to achieve. Ultimately, limited-slip differentials provide better acceleration, cornering, and overall performance, making them a worthy upgrade for any car enthusiast.
Types of Limited Slip Differential
In the automotive world, limited slip differential (LSD) refers to the type of differential that can prevent power loss by transferring torque to the wheels with better grip. There are different types of LSD available in the market, each designed to cater to specific driving needs. Let’s take a look at the different types of limited slip differential:
- Torsen (Torque Sensing) Differential: This type of differential works by using worm gears instead of clutch packs. Unlike other LSDs, it does not allow for one wheel to completely lock up. Instead, it modulates torque to balance power to the wheels with the most grip. This results in a more predictable handling characteristic, but may not be as helpful in very low traction situations.
- Clutch-Type Differential: This LSD uses a series of clutch packs to transfer torque from the spinning wheel to the one with better traction. Most clutch-type LSDs can be adjusted to be more aggressive or more relaxed, depending on your driving preferences.
- Viscous Differential: A viscous LSD works by using a viscous fluid to “lock up” the LSD when wheel slip occurs. The benefits of this type of LSD are that they are wear-free, have no clutches to wear out, and are typically very smooth in operation. When one wheel slips, the viscous fluid heats up and becomes more resistant, effectively locking the differential and sending power to the wheel with more traction.
Conclusion
Choosing the right type of limited slip differential for your car depends on your driving style, budget, and the performance characteristics you want to achieve. When deciding which LSD to install, it is essential to understand the difference between the types of limited slip differentials available in the market so that you can make an informed decision.
| Type of Limited Slip Differential | Pros | Cons |
|---|---|---|
| Torsen Differential | Predictable handling, less wear and tear | Might not be as helpful in low traction situations |
| Clutch-Type Differential | Adjustable, more affordable | Wear and tear on clutch packs |
| Viscous Differential | Smooth in operation, wear-free | Less predictable, needs to heat up to activate |
Whether you’re racing or just seeking better grip on twisty roads, getting a limited slip differential is a smart upgrade for your car. By choosing the right type of LSD, you will not only improve traction but also achieve more predictable handling and better overall performance.
Benefits of having limited slip differential
One of the essential components of a vehicle’s drivetrain system is the differential. It is the component that enables the wheels to rotate at different speeds, which is necessary for turning corners. The standard differential used in most vehicles distributes power evenly to the wheels, which can be problematic in certain situations.
The limited slip differential (LSD) is an alternative to the standard differential. It is designed to improve traction and give the driver more control over the vehicle. There are several benefits of having an LSD in your vehicle, including:
- Better Traction on Slippery Surfaces: LSDs are designed to transfer power to the wheel with the most grip. This means that in slippery conditions, such as rain, snow, or ice, an LSD will provide better traction and prevent the vehicle from losing control.
- Improved Acceleration: When accelerating quickly, the LSD will keep both wheels engaged, ensuring maximum traction and better acceleration.
- Increased Stability: In high-speed turns, the LSD will transfer power to the outside wheel, improving stability and preventing the inside wheel from losing traction.
- Reduced Wheel Spin: LSDs reduce the amount of wheel spin, which can save on tire wear and increase fuel efficiency.
- Off-Road Capability: LSDs can also be beneficial for off-road driving, where traction is critical. In situations such as rock crawling, an LSD can provide enough torque to keep the vehicle moving forward.
Types of Limited Slip Differentials
Limited slip differentials are available in several different types. Each type has its own unique characteristics and is designed for specific applications. The most common types of LSDs are:
- Torsen Differential: Torsen is short for “torque sensing.” These differentials use worm gears to transfer power to the wheel with the most grip. They are known for their durability and efficiency and are often used in high-performance vehicles.
- Clutch-Type Differential: Clutch-type LSDs use friction plates to transfer power. When one wheel begins to slip, the friction plates lock together, transferring power to the wheel with more grip. These differentials are often used in front-wheel-drive vehicles.
- Viscous Differential: Viscous LSDs use fluid to transfer power. When one wheel begins to slip, the fluid creates resistance, transferring power to the wheel with more traction. These differentials are often used in all-wheel-drive vehicles.
Conclusion
Overall, the limited slip differential is an excellent addition to any vehicle. It improves traction, acceleration, and stability and can be beneficial in a variety of driving conditions. With several different types to choose from, LSDs can be tailored to fit the specific needs of any driver.
| Type of LSD | Advantages | Disadvantages |
|---|---|---|
| Torsen | Durable, Efficient, Good for High-Performance Vehicles | Expensive, Not Ideal for Extreme Off-Road Conditions |
| Clutch-Type | Reliable, Cost-Effective, Ideal for Front-Wheel-Drive Vehicles | Requires Maintenance, Can Be Noisy or Unpredictable |
| Viscous | Smooth Operation, Good for All-Wheel-Drive Vehicles | Less Durable, Can Overheat in Extreme Conditions, Expensive |
When considering upgrading your vehicle’s differential, it is essential to weigh the advantages and disadvantages of each type of LSD. This will help you choose the right LSD for your needs and ensure that your vehicle performs optimally in the conditions you expect to encounter.
How Limited Slip Differential Reduces Wheel Spin
Limited slip differential (LSD) is a type of differential that helps control wheel spin and improve traction in slippery driving conditions.

Difference between limited slip differential and locking differential
When it comes to improving the performance of your vehicle, selecting a differential that better fits your driving style and conditions can make a significant difference. However, with all the options available, it’s easy to get confused about the difference between limited slip differential (LSD) and locking differential (LD).
- Functionality: While both LSD and LD distribute power between the wheels, they operate differently. LSD transfers power from a spinning wheel to a wheel with better traction, allowing them to rotate at similar speeds. LD locks both wheels together, ensuring equal torque and rotation.
- Driving Conditions: LD is best-suited for challenging off-road terrains, rock-crawling, and extreme situations where maximum traction is a must. On the other hand, LSD performs well in slippery or gravel-strewn roads, wet or icy conditions, and racetracks.
- Risks: While LD provides maximum traction and helps you get out of sticky situations, it can lead to instability and uneven wear and tear on tires, causing overheating and damage. Thus, it’s crucial to use LD only in specific conditions. LSD, on the other hand, is less aggressive and more consistent in power transfer, limiting the risk of tire damage.
Ultimately, choosing between LSD and LD depends on your purpose, driving habits, and conditions. While LD may seem appealing, it may not be the best choice for daily driving or other situations where it can compromise safety and stability. LSD, on the other hand, provides more versatile and consistent performance overall.
Understanding the differences between LSD and LD is crucial for making an informed decision about your vehicle’s differential system. Make sure to consult with a mechanic or a differential expert to determine which differential type is best for you.
