When it comes to building high-performance vehicles that exceed 500 horsepower, selecting the right limited slip differential is crucial. Two popular options in the market are the Eaton TrueTrac and the Detroit Locker. This article will compare these two differentials to help you make an informed decision for your build.
Understanding Limited Slip Differentials
Limited slip differentials (LSD) are designed to improve traction by allowing some degree of wheel slip while ensuring that power is distributed to both wheels. This is essential for high-performance builds, especially when dealing with significant horsepower.
Eaton TrueTrac Overview
The Eaton TrueTrac is a gear-driven limited slip differential that uses a unique design to provide smooth operation and reliable performance. It is known for its durability and effectiveness in various driving conditions.
Key Features of Eaton TrueTrac
- Gear-Driven Design: Offers consistent performance without the need for clutches.
- Automatic Engagement: Engages automatically when needed, providing seamless traction.
- Durability: Built to withstand high torque and power applications.
Detroit Locker Overview
The Detroit Locker is a locking differential that provides 100% lockup under acceleration. This means that both wheels turn at the same speed, maximizing traction in a straight line.
Key Features of Detroit Locker
- Full Locking Capability: Ensures both wheels receive equal power during acceleration.
- Strong Construction: Designed for extreme conditions and high horsepower applications.
- Predictable Behavior: Engages and disengages based on throttle input, providing a reliable performance.
Comparative Analysis
When comparing the Eaton TrueTrac and the Detroit Locker, several factors come into play, including performance, ease of use, and application suitability.
Performance
The Eaton TrueTrac excels in providing smooth engagement and is ideal for both street and off-road applications. It allows for better handling in turns, making it suitable for vehicles that are driven on a variety of surfaces.
On the other hand, the Detroit Locker is designed for maximum traction during acceleration, making it a favorite among drag racers and off-road enthusiasts who need reliable lockup.
Ease of Use
The Eaton TrueTrac is easier to handle in everyday driving situations, as it does not lock up completely during turns. This makes it more user-friendly for daily drivers.
Conversely, the Detroit Locker can be more challenging to manage during tight turns, as it locks both wheels, which can lead to increased tire wear and handling difficulties.
Application Suitability
The Eaton TrueTrac is well-suited for performance street cars, off-road vehicles, and trucks that need a balance of traction and drivability. Its versatility makes it a popular choice among enthusiasts.
The Detroit Locker is best suited for dedicated race cars or off-road vehicles where maximum traction is a priority, and the handling characteristics of a street vehicle are less of a concern.
Conclusion
Choosing between the Eaton TrueTrac and the Detroit Locker ultimately depends on your specific needs and driving style. For a balance of performance and everyday usability, the Eaton TrueTrac is an excellent choice. However, if your primary focus is on racing or extreme off-road conditions, the Detroit Locker may be the better option.
Both differentials offer unique advantages, so consider your vehicle’s application and your driving preferences when making your decision.
