The Ford S550 Mustang is celebrated for its remarkable performance, but to truly unlock its full potential, tuning the Tracklock system is essential. This guide to S550 Tracklock tuning will explore the inner workings of the Tracklock, the advantages of fine-tuning it, and how you can enhance both performance and handling to suit your driving preferences.
Whether you’re just getting started or you’re a seasoned performance enthusiast, this guide offers valuable tuning strategies and insights to elevate your Mustang’s capabilities.
Getting to Know the S550 Tracklock System: The Key to Optimal Traction
Before diving into any adjustments, it’s important to understand what the S550 Tracklock system does and how it affects your vehicle’s overall performance. The Tracklock is a specialized limited-slip differential (LSD) designed for the Ford S550 Mustang. It helps improve traction by evenly distributing power between the rear wheels during acceleration.
In simple terms, the Tracklock ensures that both rear wheels receive the same amount of power, giving you superior grip during acceleration, cornering, or on uneven terrain. Unlike a standard differential, which may send power to the wheel with the least resistance (often causing wheel spin), the Tracklock enhances stability by optimizing power distribution.
Why Tuning the S550 Tracklock System Matters
Customizing your Mustang’s performance goes beyond engine tuning; adjusting the Tracklock system is a crucial step. Tuning this component allows you to control how your Mustang behaves on the road or track.
Whether you’re aiming for quicker acceleration, sharper cornering, or more precise handling, tuning the Tracklock can help you achieve your desired driving experience. Some of the main benefits include:
- Improved Traction: Ensures even power distribution to both rear tires for better acceleration.
- Optimized Handling: Allows adjustments to make your Mustang’s turns more responsive and fluid.
- Increased Durability: Proper tuning reduces unnecessary stress, helping extend the life of the differential and tires.
How the S550 Tracklock System Operates
The Tracklock system in the S550 Mustang uses a clutch-based mechanism that engages when one wheel slips, ensuring both wheels rotate at the same speed. This significantly boosts traction, especially during demanding driving scenarios like track racing, drag racing, or spirited driving on the street.
Grasping the mechanics behind the Tracklock system is vital for maximizing its performance through tuning. It’s designed to provide enhanced traction, giving you greater control, particularly in high-performance driving situations.
Stock vs. Tuned S550 Tracklock: How They Compare
The factory-installed Tracklock system on the S550 Mustang delivers reliable performance, but tuning it offers a considerable boost. The stock settings are intended for general driving comfort, but they may not provide the level of performance you want for more aggressive driving.
By tuning the Tracklock, you gain the ability to modify critical parameters for a more personalized driving experience, including:
- Locking Speed: Adjust how quickly the system reacts when a wheel starts to slip.
- Torque Distribution: Control the torque sent to each rear wheel based on driving conditions.
With tuning, you’ll have more precise control over your Mustang’s performance, allowing you to tailor its behavior to match your driving style.
A Step-by-Step Approach to Tuning the S550 Tracklock
To properly tune the S550 Tracklock system, several components must be adjusted to influence how the differential operates. Here’s a detailed breakdown of the tuning process:
Adjusting Clutch Pack Preload for Optimized Performance
The preload setting on the clutch pack determines how quickly the differential locks and unlocks. By adjusting this, you can customize the system to be either aggressive or smooth in its operation.
- Higher Preload: Results in faster locking, ideal for performance driving or track use.
- Lower Preload: Provides smoother transitions, better for daily driving on the streets.
Modifying the Spring Rate for Desired Locking Action
The spring rate determines the pressure applied to the clutch packs, affecting how rapidly the differential locks. Stiffer springs cause a quicker lock, while softer springs result in a more gradual engagement.
- Stiffer Springs: Perfect for high-performance driving such as drag racing.
- Softer Springs: Best for everyday driving, offering more controlled engagement.
Fine-Tuning with Shim Setup for Precision Locking
Shimming the differential allows you to adjust how tightly the clutch pack is compressed, thus modifying how fast or slow it locks. More shims result in quicker lock-ups, while fewer shims lead to slower, smoother engagement.
- Addition of Shims: Ideal for faster lock-ups in high-performance driving situations.
- Removal of Shims: Creates smoother transitions between locked and unlocked states, ideal for casual driving.
Essential Tools Needed for S550 Tracklock Tuning
To ensure that the tuning process is both safe and effective, having the proper tools is crucial. Here’s a list of the basic tools you’ll need for tuning the S550 Tracklock system:
- Socket Wrenches
- Differential Fluid
- Shim Kit
- Torque Wrench
- Differential Rebuild Kit (if replacing parts)
Having these tools will ensure that your adjustments are made safely and precisely. If you’re making more extensive modifications, you may also need specialized tools such as a clutch pack press.
Best Practices for Tuning the S550 Tracklock System
Here are some important tips to follow when tuning your Tracklock system:
Take a Gradual Approach
If you’re new to tuning, avoid making drastic changes all at once. Make gradual adjustments so you can evaluate how each change impacts the system and maintain control over the vehicle’s handling.
Test Regularly for Optimal Results
After each adjustment, take your Mustang out for a test drive to assess the changes. Does it accelerate faster? Does it handle better in corners? Regular testing helps you fine-tune the system for peak performance.
Perform Routine Maintenance to Extend System Life
Maintaining your S550 Tracklock system is crucial for long-term reliability. Regularly check the differential fluid and replace worn components. Routine upkeep will ensure the system operates smoothly and extends its lifespan.

Once you’ve fine-tuned your S550 Tracklock, expect noticeable improvements in how your Mustang performs. Here’s what tuning can bring:
- Improved Traction: Experience better grip, especially during acceleration and when navigating tough, uneven surfaces.
- Optimized Cornering: Enjoy enhanced stability and control through tight corners, even at high speeds.
- Increased Overall Performance: A properly tuned Tracklock gives you a competitive advantage, boosting your performance in drag races and track events.
Pitfalls to Avoid When Tuning Your S550 Tracklock
Even skilled tuners can make mistakes while fine-tuning the Tracklock system. Be mindful of these common missteps:
Excessive Tightening of the Clutch Pack
Over-tightening can lead to premature wear, which can affect the longevity of your differential and tires. Always make small adjustments and test after each change.
Overlooking Differential Fluid Maintenance
Using old or inadequate differential fluid can hinder your Tracklock’s efficiency. Make sure the fluid is fresh and at the correct level before starting any tuning work.
Forgetting to Rebalance the Vehicle After Adjustments
Adjustments to the differential can affect your car’s overall balance. After tuning, be sure to rebalance the suspension and tires to preserve smooth handling and performance.
