Understanding the Truetrac Differential
The Truetrac differential is a gear-driven limited-slip differential that provides improved traction and stability. Unlike traditional open differentials, the Truetrac uses a unique design that allows for better power distribution to the wheels, especially during acceleration. This is particularly beneficial during drag racing, where maximizing grip is crucial for achieving optimal times.
Installation Process
Installing the Truetrac differential in my Mustang GT was a straightforward process, but it did require some mechanical knowledge and tools. Here’s a brief overview of the steps I took:
- Gather necessary tools and parts, including the Truetrac differential, new gear oil, and installation kit.
- Lift the vehicle and remove the rear axle assembly.
- Disassemble the old differential and clean the housing.
- Install the Truetrac differential according to the manufacturer’s instructions.
- Reassemble the axle, ensuring all components are secured properly.
- Fill the differential with new gear oil and check for leaks.
Initial Testing and Results
After completing the installation, I was eager to test the Truetrac differential on the drag strip. My first runs were eye-opening. Prior to the installation, my Mustang GT struggled with wheel spin and inconsistent launches. However, with the Truetrac in place, I experienced a significant improvement in traction.
Before the Upgrade
Before the upgrade, my best drag race time was around 12.5 seconds in the quarter mile. I often faced challenges with traction, especially during hard launches, which resulted in slower times and frustration.
After the Upgrade
After installing the Truetrac differential, my times improved dramatically. I was able to achieve a best quarter-mile time of 11.9 seconds. The difference in performance was astounding, and I could feel the increased grip right off the line.
Benefits of the Truetrac Differential
The Truetrac differential offers several distinct advantages for drag racing enthusiasts:
- Enhanced Traction: The gear-driven design provides better power distribution, minimizing wheel spin.
- Improved Launch Consistency: With better grip, launches become more consistent, leading to better overall times.
- Durability: The Truetrac is built to withstand high-performance applications, making it a reliable choice for racing.
- Easy Maintenance: The design allows for straightforward maintenance, ensuring long-term performance.
Comparing with Other Differential Options
While there are various differential options available for the Mustang GT, the Truetrac stands out for its unique features. Here’s how it compares to other popular choices:
- Open Differential: Provides no traction benefits, leading to wheel spin and slower times.
- Standard Limited-Slip Differential: Offers some traction improvement but may not be as effective as the Truetrac in high-performance situations.
- Torque-Vectoring Differential: Provides advanced traction control but at a higher cost and complexity.
Real-World Experiences from Other Mustang GT Owners
To further validate the effectiveness of the Truetrac differential, I reached out to other Mustang GT owners who have made the same upgrade. Their experiences echoed my results:
- Many reported similar improvements in traction and launch consistency.
- Several owners noted a decrease in 0-60 times, attributing this to the enhanced grip.
- Feedback highlighted the Truetrac’s reliability, with many stating it performed well even under extreme racing conditions.
Conclusion
Upgrading to a Truetrac differential has been one of the best modifications I’ve made to my Mustang GT for drag racing. The real-world results speak for themselves, with significant improvements in traction, launch consistency, and overall performance. If you’re looking to enhance your drag racing experience, I highly recommend considering the Truetrac differential as a worthy investment.
