Show original supplier description
The ACT SB3-HDSS is a heavy-duty clutch disc engineered to surpass OEM specifications, offering enhanced torque capacity and longevity for your vehicle's clutch system. This component serves as a direct replacement for the disc included in ACT clutch kits, providing an economical solution for replacing worn friction material. This clutch disc is specifically designed for the 2002-2005 Subaru WRX. It features a sprung street disc design and a heavy-duty rating, capable of holding up to 434 ft-lbs of torque. This makes it suitable for drivers seeking a more robust clutch solution that can handle increased power output. The ACT SB3-HDSS offers a way to refresh your existing ACT clutch kit without needing to purchase an entirely new assembly.
