The Ford Focus RS is known for its impressive performance and handling, but to maximize its potential, especially during launches, enhancing the power transfer to the wheels is crucial. One effective upgrade is the installation of a Truetrac Limited Slip Differential (LSD). This article will guide you through the benefits of this modification and the steps involved in the installation process.
Understanding Limited Slip Differentials
A Limited Slip Differential (LSD) is designed to improve traction by allowing some difference in wheel speed between the left and right wheels while still transferring power effectively. This is particularly beneficial in high-performance vehicles like the Ford Focus RS, where optimal power delivery is essential for acceleration and cornering.
Benefits of Installing a Truetrac LSD
- Improved Traction: The Truetrac LSD distributes power to the wheel with the most grip, reducing wheel spin during launches.
- Enhanced Cornering: By allowing for differences in wheel speed, the Truetrac LSD improves handling and stability in corners.
- Durability: Truetrac differentials are built to withstand high performance demands, making them a reliable choice for enthusiasts.
- Easy Maintenance: Unlike some other LSDs, the Truetrac requires minimal maintenance and is straightforward to install.
Preparing for Installation
Before starting the installation process, gather all the necessary tools and parts. Here’s a list of what you will need:
- Truetrac LSD kit
- Socket set
- Torque wrench
- Jack and jack stands
- Fluid for the differential
- Safety glasses and gloves
Step-by-Step Installation Process
1. Prepare the Vehicle
Start by parking the Ford Focus RS on a flat surface. Make sure to engage the parking brake. Use a jack to lift the rear of the vehicle and secure it with jack stands. This will provide you with adequate access to the rear differential.
2. Remove the Rear Differential Cover
Using a socket set, remove the bolts securing the rear differential cover. Carefully pry the cover away from the differential housing to avoid damaging the gasket. Allow the old fluid to drain completely into a suitable container.
3. Remove the Old Differential
Once the fluid is drained, remove the ring gear bolts and the old differential. Carefully slide it out of the housing, taking note of how it is positioned for reinstallation.
4. Install the Truetrac LSD
Position the Truetrac LSD into the differential housing. Ensure it is seated properly and aligned with the ring gear. Reinstall the ring gear bolts and torque them to the manufacturer’s specifications.
5. Reattach the Differential Cover
Apply a new gasket or sealant to the differential cover. Reattach the cover and secure it with the bolts. Make sure to torque them to the correct specifications to prevent leaks.
6. Fill with Differential Fluid
Using a funnel, fill the differential with the appropriate fluid as specified in the Truetrac LSD installation manual. Be sure to fill it to the correct level to ensure proper operation.
7. Lower the Vehicle and Test Drive
Carefully lower the vehicle back to the ground. Start the engine and take the Ford Focus RS for a test drive. Pay attention to how the car handles during acceleration and cornering. You should notice improved traction and power transfer immediately.
Conclusion
Installing a Truetrac LSD on your Ford Focus RS can significantly enhance your vehicle’s performance, especially during launches and aggressive driving. By following the steps outlined above, you can enjoy better power transfer and improved handling, making your driving experience more enjoyable and exciting.
