Understanding the S550 Tracklock System
The S550 Mustang features a limited-slip differential (LSD) known as the Trac-Lok. Unlike an open differential that allows wheels to spin at different speeds, the Trac-Lok uses clutch packs to distribute power more evenly to the rear wheels, improving traction during acceleration and cornering. The Trac-Lok system incorporates ramp angles within its design. These angles determine how much torque is needed to activate the clutch packs and lock the differential. Understanding the role of ramp angles and clutch packs is crucial for tuning your S550 Tracklock system. By adjusting these components, you can fine-tune the level of locking and optimize the differential’s performance for your specific driving needs and track conditions.
Trac-Lock vs. Torsen Differentials
The S550 Mustang offers two main types of LSDs⁚ Trac-Lok and Torsen. While both aim to improve traction, they achieve this using different mechanisms. Trac-Lok, a clutch-type LSD, utilizes a set of clutch packs that engage when one wheel starts to slip. The Torsen, a helical gear-type LSD, uses a series of gears to distribute torque based on wheel speed differences. Trac-Lok is known for its versatility and adjustability, allowing for tuning to match specific driving preferences. It is generally more affordable than a Torsen differential. However, Torsen units are often favored for their smoother and more predictable operation, particularly in high-performance applications. The choice between Trac-Lok and Torsen depends on your priorities and the intended use of your Mustang. While Trac-Lok offers tuning flexibility, Torsen excels in performance and predictability.

Tuning Techniques
Tuning your S550 Tracklock differential involves a few key techniques that can dramatically alter its behavior and performance. One common technique is adjusting the ramp angle. This refers to the angle of the ramps within the differential, which controls how much force is required to lock the differential. Adjusting the ramp angle can be achieved by installing aftermarket ramp plates or shims. Another tuning technique involves replacing the clutch packs. These packs are responsible for transferring power between the wheels. Replacing worn or damaged clutch packs with high-performance units can improve the differential’s locking force and overall efficiency. Finally, some enthusiasts opt for complete differential upgrades, such as replacing the stock Trac-Lok with a Torsen differential. Torsen differentials are known for their superior locking characteristics and can offer significant performance benefits. Ultimately, the best tuning techniques for your S550 Tracklock system will depend on your specific driving style, track conditions, and desired performance goals.
Ramp Angle Adjustment
Adjusting the ramp angle is a popular tuning technique for S550 Tracklock differentials, offering a direct way to control the differential’s locking behavior. The ramp angle determines the force required to engage the differential, influencing how it distributes power between the wheels. Increasing the ramp angle makes the differential more aggressive, locking up sooner and providing greater traction. Conversely, decreasing the ramp angle makes the differential less aggressive, requiring more force for engagement. This can be advantageous in situations where you want a more subtle, controlled lockup. Adjusting the ramp angle is typically achieved by installing aftermarket ramp plates or shims, available from various performance parts suppliers. However, it’s crucial to note that improper ramp angle adjustment can lead to unwanted side effects, such as excessive wear on the differential components. Therefore, it’s highly recommended to consult with a qualified professional or consult detailed instructions before attempting any ramp angle adjustments.
Clutch Pack Replacement
For those seeking a more significant improvement in their S550 Tracklock differential’s performance, replacing the clutch pack is a viable option. The clutch pack is responsible for generating the friction that locks the differential, and over time, it can wear down, reducing the differential’s effectiveness. Replacing the clutch pack with a higher-performance unit, often made from materials like carbon fiber or ceramic, can dramatically enhance the locking force and provide greater traction. This upgrade is especially beneficial for track-focused Mustangs, where the differential is subjected to heavy loads and frequent engagement. However, clutch pack replacement is a more involved process, requiring specialized tools and knowledge. It’s generally recommended to seek the services of a professional mechanic or a reputable performance shop for this task. Proper installation and adjustment are critical for optimal performance and longevity of the differential.
