Trac-Lok Vs. Truetrac

You’ve probably heard of Trac-Lok and Truetrac, two popular differential options for off-road enthusiasts. But which one is the better choice for your vehicle? In this article, we’ll compare Trac-Lok and Truetrac, highlighting their key features, benefits, and limitations. By the end, you’ll have a clearer understanding of these two options, helping you make an informed decision when it comes to upgrading your vehicle’s differential. So let’s dive in and explore the differences between Trac-Lok and Truetrac!

1. Overview

1.1 What are Trac-Lok and Truetrac?

Trac-Lok and Truetrac are two types of limited-slip differentials commonly used in vehicles. Limited-slip differentials are designed to distribute torque evenly between the two wheels on an axle, providing improved traction in challenging driving conditions. Trac-Lok and Truetrac are both popular options for off-road enthusiasts and those looking for enhanced performance on various terrains.

Trac-Lok, also known as Trac-Lok Limited Slip Differential (LSD), is a mechanical system that uses a series of clutches to control the power distribution between the wheels. When one wheel begins to slip, the Trac-Lok differential engages the clutches, sending more torque to the wheel with better traction. This improves the vehicle’s ability to navigate through uneven surfaces, such as mud, gravel, or snow.

On the other hand, Truetrac is a helical gear-driven limited-slip differential. Instead of using clutches, it utilizes gears to transfer power to the wheel with better traction. This unique design allows for full driveline differentiation when needed, resulting in smoother engagement and improved handling. Truetrac is often favored for its quiet operation and superior performance in a wide range of driving conditions.

1.2 Purpose of the Comparison

The purpose of this comparison is to provide you with a comprehensive understanding of the differences and similarities between Trac-Lok and Truetrac differentials. By examining their functionality, traction control mechanisms, performance on different terrains, availability, compatibility, installation process, maintenance requirements, and cost, you will be able to assess which option best suits your specific needs and preferences.

2. Functionality

2.1 How Trac-Lok Works

Trac-Lok operates by utilizing a set of clutches to regulate the torque distribution between the two wheels on an axle. When one wheel slips, typically due to a lack of traction, the Trac-Lok differential engages the clutches. This causes more torque to be transferred to the wheel with better traction, allowing the vehicle to maintain forward momentum. The clutches are designed to limit the slip to a certain predetermined level, providing a balance between improved traction and ride comfort.

2.2 How Truetrac Works

Truetrac, unlike Trac-Lok, employs a helical gear design to distribute power between the wheels. The gear-driven mechanism permits a varying amount of torque to be transmitted to each wheel, depending on the available traction. This intelligent design ensures that power is delivered to the wheel with the best grip, improving overall traction and handling. The operation of Truetrac is seamless and mechanical, without the need for clutches or friction plates.

3. Differential Type

3.1 Type of Differential for Trac-Lok

Trac-Lok is a limited-slip differential (LSD). Limited-slip differentials are designed to distribute torque between the wheels, rather than allowing one wheel to spin freely while the other remains stationary. The clutch-based system employed by Trac-Lok offers a predetermined amount of slippage before engaging, providing improved traction while maintaining drivability.

3.2 Type of Differential for Truetrac

Truetrac is also a limited-slip differential (LSD), but it utilizes a helical gear design instead of clutches. The gear-driven mechanism provides a smooth and continuous transfer of torque between the wheels, allowing for greater traction and control. This unique design makes Truetrac particularly well-suited for various terrains and driving conditions.

4. Traction Control

4.1 Traction Control Mechanism in Trac-Lok

In Trac-Lok differentials, the primary mechanism for controlling traction is through the use of clutches. When slippage occurs, the clutches engage, transferring torque to the wheel with better traction. The design of Trac-Lok allows for some degree of slip before it applies the clutches, ensuring a comfortable driving experience while still providing improved traction.

4.2 Traction Control Mechanism in Truetrac

Truetrac differentials utilize the helical gear design to maintain traction control. The gear-driven mechanism ensures that power is distributed to the wheel with better grip, utilizing the available traction effectively. This results in enhanced overall control and stability, as the differential automatically adapts to the varying driving conditions and traction requirements.

5. Performance on Different Terrains

5.1 Off-Road Performance

When it comes to off-road performance, both Trac-Lok and Truetrac differentials offer significant advantages. Trac-Lok’s clutch-based system provides an excellent balance between improved traction and drivability. It excels in muddy, snowy, or gravelly terrains where wheel slippage is common. The ability of Trac-Lok to transfer torque to the wheel with better traction ensures that your vehicle can power through challenging off-road conditions.

Truetrac, with its gear-driven design, also delivers impressive off-road performance. The smooth and seamless transfer of power between the wheels allows for better traction and control on uneven terrains. The differential’s responsiveness to changing traction conditions ensures maximum traction when navigating rocky or uneven surfaces.

5.2 On-Road Performance

Both Trac-Lok and Truetrac differentials offer improved on-road performance compared to open differentials. Trac-Lok provides enhanced traction on slippery or wet roads, reducing the likelihood of wheel spin and improving overall stability. It is especially beneficial for vehicles that often encounter changing road conditions, such as those driven in regions with frequent rain or snow.

Truetrac also performs admirably on paved surfaces. Its gear-driven mechanism allows for smooth and seamless power transfer between the wheels, resulting in improved handling and stability. Truetrac’s ability to adapt to different driving conditions makes it an excellent choice for drivers seeking enhanced on-road performance without sacrificing off-road capability.
