Considerations for Clutch Installation
Before beginning the installation process, it is important to consider several factors that can affect the success of the project. These include the tools and materials required, the condition of the existing components, and the specific instructions for the selected ACT clutch kit.
Tools and Materials
Clutch installation typically requires a set of basic tools, including a floor jack, jack stands, a torque wrench, and a clutch alignment tool. Additional tools may be necessary depending on the specific vehicle model and clutch kit. It is also important to ensure that all necessary components, such as the pressure plate, flywheel, and clutch disc, are included in the kit.
Vehicle-Specific Fitment
ACT Clutch kits are designed for specific vehicle models, and it is important to ensure that the selected kit is compatible with the vehicle in question. The ACT Clutch website provides detailed information on fitment and compatibility, which should be reviewed before beginning the installation process.
Preparation and Safety
Prior to installation, the vehicle should be raised and securely supported on jack stands. It is also important to disconnect the battery and ensure that the vehicle is in neutral. Proper preparation and adherence to safety protocols can help prevent accidents and ensure a smooth installation process.
Installation Steps
While the exact steps may vary depending on the specific ACT clutch kit and vehicle model, the general process for clutch installation typically involves the following:
Removing the Transmission: The first step in the installation process is to remove the transmission. This may involve disconnecting the driveshaft, removing the transmission crossmember, and loosening the transmission bolts.
Removing the Old Clutch Assembly: Once the transmission is removed, the old clutch assembly can be taken out. This involves removing the pressure plate and clutch disc and inspecting the flywheel for wear or damage.
Inspecting and Preparing the Flywheel: If the flywheel is damaged or worn, it should be replaced or resurfaced. A smooth, even surface is essential for proper clutch function.
Installing the New Clutch Kit: The new ACT clutch kit can then be installed. This involves placing the clutch disc in the correct position and securing the pressure plate with the appropriate bolts. It is important to follow the manufacturer's torque specifications to ensure that all components are properly tightened.
Reinstalling the Transmission: Once the new clutch is installed, the transmission can be reinstalled. This involves aligning the transmission with the clutch and securing it in place with the appropriate bolts.
Final Adjustments and Testing: After the installation is complete, it is important to make any necessary adjustments and test the clutch to ensure that it functions as intended.
User Experiences and Installation Tips
Installation experiences can vary depending on the installer’s level of experience and the specific vehicle model. However, there are several tips that can help ensure a successful installation.
Familiarity with the Vehicle
If you are installing a clutch in a Honda or Acura model, it is important to be familiar with the specific components and procedures involved. For example, users have reported that installing a clutch in a 2020 Civic Si model can be challenging due to the tight fit and limited space. It is important to have a clear understanding of the vehicle’s layout and to take the time to carefully follow the manufacturer's instructions.
Time and Patience
Clutch installation can be a time-consuming process, and it is important to allow sufficient time for the project. Users who have installed ACT clutch kits report that the process can take anywhere from a few hours to an entire day, depending on the complexity of the installation and the experience level of the installer.
Working on the Ground
If the installation is being done on the ground, it is important to have a clear, well-lit workspace and to ensure that the vehicle is securely supported. Working on the ground can be more challenging than working on a lift, but it can be done with the right tools and preparation.
Following Manufacturer Instructions
ACT Clutch provides detailed instructions for each of its clutch kits, and it is important to follow these instructions carefully. The instructions include information on torque specifications, installation steps, and compatibility information, which should be reviewed before beginning the installation process.

ACT Clutch kits are designed for a variety of applications, and it is important to ensure that the selected kit is compatible with the vehicle in question. The company offers a range of clutch kits for different vehicle models and engine types, and it is important to select the correct kit for the specific application.
Torque Capacity
One of the key factors to consider when selecting an ACT clutch kit is the torque capacity. The torque capacity refers to the maximum amount of torque that the clutch can handle before slipping. ACT Clutch kits are designed for a range of torque capacities, and it is important to select a kit that is appropriate for the vehicle's power output.
Heat Resistance
ACT Clutch kits are also designed to handle high levels of heat, which is essential for vehicles that experience frequent clutch usage. The 6 Puck Clutch, for example, is known for its superior heat resistance, making it ideal for track-focused applications.
Durability
ACT Clutch kits are engineered for durability and long-term performance. The HDSS Clutch, for example, is designed for daily drivability while still providing excellent durability. This makes it ideal for drivers who want a clutch that can handle both street and track use without compromising comfort.
Conclusion
ACT Clutch offers a range of high-performance clutch kits designed for a variety of applications. From the 6 Puck Clutch for track-focused vehicles to the HDSS Clutch for daily drivers, each model is engineered to provide reliable performance and enhanced torque capacity. When installing an ACT clutch, it is important to follow the manufacturer's instructions carefully and to ensure that the selected kit is compatible with the vehicle in question. With proper preparation and installation, an ACT clutch can provide years of reliable service and improved performance.
