• Installation hardware

In mid-2018, Subaru updated the WRX clutch from 230mm to 240mm to improve durability. This larger setup became the standard for the 2018–2021 model years.

Check the last seven digits of your VIN to determine if this kit fits:

• If your VIN is J*806877 or higher:
  
  • Your car has the larger 240mm factory setup.
  • This clutch kit is compatible with your OEM flywheel.
  • Note: This kit will not fit the Action Clutch chromoly flywheel AC105FW.
    

• If your VIN is J*806876 or lower:
  • Your car has the older 230mm factory setup.
  • This clutch kit will not fit your car.
  • To use an Action Clutch product, you would need to run their 2015–2018 WRX clutch and flywheel combination instead.

Installation

Professional installation is strongly recommended as clutch replacement requires transmission removal, specialized tools, and torque specifications. Installation typically takes 4-6 hours and requires proper flywheel resurfacing or replacement. Clutch break-in period of 500-1000 miles is recommended for optimal performance and longevity.
