The Ultimate S550 Tracklock Tuning Guide: A Step-by-Step Approach to Optimizing Your Mustang’s Performance
The Ford S550 Mustang is renowned for its exceptional performance, but to truly unleash its power, tuning the Tracklock system is a game-changer. In this S550 Tracklock Tuning Guide, we will explore the key elements of the Tracklock system, the benefits of tuning it, and how you can improve both performance and handling to match your driving style.
Whether you’re a novice enthusiast or a seasoned gearhead, this guide will provide practical insights and tuning techniques to enhance your Mustang’s capabilities.
Understanding the S550 Tracklock System: The Backbone of Your Mustang’s Traction
Before diving into tuning, it’s essential to grasp what the S550 Tracklock system is and how it impacts your vehicle’s performance. The Tracklock is a limited-slip differential (LSD) designed specifically for the Ford S550 Mustang. It enhances traction by distributing power evenly between the rear wheels during acceleration.
In essence, it ensures both rear wheels receive equal power, providing better grip when cornering, accelerating, or driving over rough surfaces. Unlike a standard differential, which typically sends power to the wheel with the least resistance (often resulting in wheel spin), the Tracklock maximizes control and stability by balancing power distribution.
Why Is Tuning the S550 Tracklock So Crucial?
Customizing your S550 Mustang’s performance is not just about power upgrades; tuning the Tracklock is equally important. By tuning this system, you can fine-tune how your Mustang behaves on the road or track.
Whether you’re aiming for a quicker launch, superior cornering, or more aggressive handling, a well-tuned Tracklock system gives you control over these aspects. The benefits of tuning include:
- Enhanced Traction: Ensures both rear tires maintain equal power, boosting acceleration.
- Optimized Handling: Adjust settings to make turns smoother and more responsive.
- Increased Component Longevity: Proper tuning reduces unnecessary wear, extending the lifespan of both the tires and the differential system.
How Does the S550 Tracklock System Function?
The S550 Tracklock uses a clutch mechanism to engage when one wheel begins to slip, ensuring both wheels rotate at an equal speed. This enhances overall traction, especially during performance driving scenarios like track days, drag racing, or spirited street driving.
Understanding the mechanics of the Tracklock system is crucial for optimizing your tuning strategy. This system helps maximize your Mustang’s traction, providing superior control during performance driving.
Stock vs. Tuned S550 Tracklock: What’s the Difference?
While the stock Tracklock system in the S550 Mustang offers solid performance, tuning it takes things to the next level. The factory settings are geared toward general driving comfort, but they might not provide the precise performance you’re looking for.
With tuning, you can adjust several variables for a more customized driving experience, such as:
- Locking Power: Modify how quickly the system reacts when wheel slip occurs.
- Torque Biasing: Fine-tune how much torque is sent to each wheel under different driving conditions.
Through tuning, you gain greater control over your Mustang’s behavior, creating a driving experience that aligns perfectly with your performance goals.
Step-by-Step Guide on How to Tune the S550 Tracklock System
To properly tune the S550 Tracklock system, it’s important to adjust multiple components that affect how the differential operates. Below is a breakdown of the tuning process:
Adjusting Clutch Pack Preload for Better Performance
The preload on the clutch pack in the Tracklock controls how quickly the differential locks and unlocks. By adjusting this setting, you can customize how aggressive or smooth the system behaves.
- Higher Preload: Results in quicker locking, ideal for aggressive driving or track racing.
- Lower Preload: Offers smoother transitions, more suited for daily street driving.
Spring Rate Adjustment: Customizing Locking Action
The spring rate determines the force applied to the clutch packs, affecting how quickly or gradually the differential locks. Stiffer springs lead to a faster locking mechanism, while softer springs provide a slower, smoother engagement.
- Stiffer Springs: Ideal for high-performance situations like drag racing.
- Softer Springs: Suited for daily driving, providing a gentler, more controlled engagement.
Fine-Tuning with Shim Setup for Precise Locking
Shimming the differential allows you to control how tightly the clutch pack is compressed, thus adjusting the locking behavior. The more shims you add, the tighter the clutch pack, resulting in quicker lock-ups.
- Add Shims: For faster lock-ups, ideal for aggressive driving.
- Remove Shims: For smoother, more gradual transitions between locked and unlocked states.
Essential Tools for S550 Tracklock Tuning
Proper tuning requires the right tools to ensure precision and safety. The following are the basic tools you’ll need to tune your S550 Tracklock system:
- Socket Wrenches
- Differential Fluid
- Shim Kit
- Torque Wrench
- Differential Rebuild Kit (optional if replacing parts)
Having the correct tools will ensure that your adjustments are safe and accurate. Some specialized tools, such as a clutch pack press, may be required depending on the extent of your tuning.
Best Practices for Tuning Your S550 Tracklock System
Start Slowly
If you’re new to tuning, avoid making drastic changes. Gradual adjustments will help you understand how each modification affects the system and prevent unpredictable handling issues.
Regular Testing for Optimal Performance
After each adjustment, take your Mustang out for a test drive. Pay attention to how it handles—does it accelerate faster? Does it grip better around corners? Regular testing will help you fine-tune your settings.
Routine Maintenance for Longevity
Regular maintenance is crucial to keeping your S550 Tracklock system running smoothly. Always check the differential fluid levels, and replace any worn-out components. Routine maintenance will help extend the lifespan of the system and maintain its performance.
What to Expect from a Tuned S550 Tracklock System
Once you tune your S550 Tracklock, you’ll notice immediate improvements in performance. Here’s what you can expect:
- Superior Traction: Improved grip during acceleration and cornering, especially on challenging surfaces.
- Enhanced Cornering: Better stability and balance when navigating tight turns at high speeds.
- Overall Performance Boost: A tuned Tracklock can help you achieve better results in drag races and track days, providing the edge needed to outperform the competition.
Common Mistakes to Avoid When Tuning the S550 Tracklock
Even experienced tuners can fall into certain traps when working on their S550 Tracklock system. Here are some mistakes to watch out for:
Over-Tightening the Clutch Pack
Excessive tightening can lead to premature wear on the differential and tires, costing you in repairs. Make gradual adjustments and test after each one.
Neglecting Differential Fluid Maintenance
Old or insufficient differential fluid can drastically impact your Tracklock’s performance. Always ensure that the fluid is fresh and at the right level before making adjustments.
Forgetting to Rebalance the Car After Tuning
Tuning the differential can affect your car’s balance. After tuning, be sure to rebalance the suspension and tires to maintain optimal handling.
