The Nissan 370Z is a popular sports car known for its performance and agility. One of the key upgrades that enthusiasts often consider is the installation of a custom-length aluminum driveshaft. This modification not only enhances the car’s performance but also contributes to weight reduction, improving overall handling. In this article, we will explore the benefits of upgrading to a custom-length aluminum driveshaft, installation tips, and the potential power gains you can expect.
Benefits of a Custom-Length Aluminum Driveshaft
Upgrading to a custom-length aluminum driveshaft offers several advantages for Nissan 370Z owners. Here are some of the key benefits:
- Weight Reduction: Aluminum driveshafts are significantly lighter than their steel counterparts, which reduces rotational mass and improves acceleration.
- Increased Power Transfer: A custom-length driveshaft can optimize power transfer from the engine to the wheels, resulting in better throttle response.
- Improved Handling: With less weight, the car’s handling dynamics are enhanced, making it more responsive during cornering.
- Reduced Vibration: Aluminum driveshafts tend to produce less vibration compared to steel, leading to a smoother driving experience.
Installation Tips for a Custom-Length Aluminum Driveshaft
Installing a custom-length aluminum driveshaft in your Nissan 370Z can be a rewarding project. Here are some tips to ensure a successful installation:
Gather Necessary Tools and Materials
Before starting the installation, make sure you have the following tools and materials:
- Socket set
- Torque wrench
- Jack and jack stands
- Safety goggles
- Custom-length aluminum driveshaft
- New U-joints (if necessary)
Preparation Steps
Proper preparation is crucial for a smooth installation process. Follow these steps:
- Ensure the car is parked on a flat surface and engage the parking brake.
- Lift the rear of the car using a jack and secure it with jack stands.
- Remove any underbody panels that may obstruct access to the driveshaft.
Removing the Old Driveshaft
To remove the old driveshaft, follow these steps:
- Locate the bolts securing the driveshaft to the differential and transmission.
- Using a socket set, remove the bolts while holding the driveshaft in place to prevent it from spinning.
- Carefully slide the driveshaft out of the transmission and differential.
- Inspect the U-joints and replace them if they show signs of wear.
Installing the Custom-Length Aluminum Driveshaft
Now it’s time to install the new driveshaft. Follow these instructions:
- Align the new driveshaft with the transmission and differential.
- Slide the driveshaft into place, ensuring that it fits snugly.
- Reattach the bolts to the differential and transmission, tightening them to the manufacturer’s specifications.
- If applicable, ensure that the U-joints are properly greased and secured.
Final Checks
After installation, perform these final checks:
- Double-check all bolts for tightness.
- Inspect the driveshaft for any signs of misalignment.
- Lower the car and take it for a test drive to ensure everything is functioning correctly.
Expected Power Gains
One of the most exciting aspects of upgrading to a custom-length aluminum driveshaft is the potential for power gains. While the exact figures can vary based on other modifications and tuning, many Nissan 370Z owners report noticeable improvements:
- Improved Acceleration: The reduction in weight allows the engine to transfer power more effectively, leading to quicker acceleration times.
- Enhanced Throttle Response: A lighter driveshaft means less inertia, resulting in a more responsive throttle.
- Better Overall Performance: With improved power transfer and reduced weight, the overall performance of the vehicle is significantly enhanced.
While the exact horsepower gains can vary, many users experience an increase in the range of 5-15 horsepower, along with improved torque delivery.
Conclusion
Upgrading to a custom-length aluminum driveshaft is a worthwhile investment for Nissan 370Z enthusiasts looking to enhance their vehicle’s performance. With benefits such as weight reduction, improved power transfer, and enhanced handling, this modification can significantly elevate your driving experience. By following the installation tips outlined in this article, you can successfully install your new driveshaft and enjoy the power gains that come with it.
