  • Preserves low-end torque and driveability
  • One piece ring gear for high durability

    Competition Clutch Lightweight Flywheel ( Part Number: 2-721-ST)
    Good product some vibration at first 2 years ago
    jeff1029074099
    I have a light drive train, aluminum, drive shaft, Perrin vibration dampener, and this light flywheel. No codes and easy to takeoff from stop. No vibrations detected, when assembled by shop. Immediately drove on 1200mile trip. When very hot and taking off the clutch made large vibration. I think the mechanics that installed parts gunned it around town before I got it. I took it easy and it is close enough to stock quiet that I'm happy. Noticed some improved revs and some more performance.

    Had it for about 500 miles. Took a little getting used to in low RPMs and RPMs drop a little more between shifts.

    Great flywheel 4 years ago
    Brett.carlson33805153
    I paired this with a Stage 3 CC clutch. I did notice more vibrations around 2700 rpms and up. Between shifts the rpms do drop a little quicker. It did make a little difference in low rpm drivability. Now with 1500 miles the vibrations have subsided and it's almost back to stock.

    No cel code, but you do have to rev it just a little higher to engauge, 200rpms max. Kinda a pain in stop and go traffic but I did the stage 2. Will update when It's broken in more.

      Will this work with an ACT extreme duty 6 puck?

        A:  This flywheel is only confirmed to fit Competition Clutch clutch kits. You will need to use ACT's flywheel with your ACT Extreme Duty 6 Puck.

    • Q: some info please  Robbie08316 months ago

      im about to make a purchase for your CC stage 4 clutch kit. im currently stock and im not that concerned about it being rough till i modify my car but would this flywheel match well with CC stage 4 clutch kit? Thank you in advance for your response!
      • 0 of 0 people found the following answer helpful

        A:  This will work well with the stage 4 kit, but puck clutches can be a bit more rough and tricky to drive, especially with a light flywheel. If your power goals are within their rating, Comp's Stage 2-3 kits will be a bit less harsh.

    • Q: N/A vs Turbo  zeus122376046022 years ago

      Greetings. I noticed that they recommend this flywheel for use on N/A setups. Why is this? Can this be run on a turbo charged car? Thanks.
    • Q: resurfacing   Ruger2 years ago

      Can this flywheel be resurfaced?
      • 0 of 0 people found the following answer helpful

        A:  Yes, but resurfaced flywheels are sometimes known to slip. We would recommend purchasing a new flywheel.
