  1. JT/JL Clutch and Flywheel explained by ACT

    Thanks for the comments. I hate the rev-hang on the newer Jeeps especially during that first 90 second warm up. In our testing I didn't notice a big increase in how long the rev hang lasts, but I sure noticed the added force from the inertia.

    I would recommend the JP6-HDSS. It is best suited for over 90% of Jeep JL/JT applications. The JP6-HDG6 meant for racing and holds over 600ftlbs. It will engage very quickly and aggressively.

  7. JT/JL Clutch and Flywheel explained by ACT

    Thanks Gatorized for the feedback. Keep in mind the lighter spring will do nothing to increase the capacity of the stock clutch., but it will improve the feel. If you are experienced clutch slippage, we have an excellent option for that.

    No, definitely not. Make sure to get the bearing back to us to inspect. Release bearings don't typically fail upon install but over time, which is why we specify a better grease and OEM Dupont plastic for our JL bearings to help them last. There are now cheaper aftermarket bearings available...
  9. "Clutch Hot Warning"... but I'm stumped as to why?

    We haven't yet, but I am sure we will. It is on the radar, but there are a ton of other projects right now.
  10. "Clutch Hot Warning"... but I'm stumped as to why?

    Looks like a totally cooked TJ/YJ clutch to me. Although it may have been over-reved causing the clutch lining to blow off. Below is an example from a buddy of mine in our 4x4 club. To protect him from embarrassment we will just call him "Dan". Dan managed to do this while the engine is idling...

    Recent testing on a Gladiator clutch with 62K shows surprising and important findings. Watch: I have to take back what I said about the OEM JL/JT clutch being adequate. This makes a good case for buying an ACT clutch and flywheel even on a stock vehicle.

    Thanks for the update. Nice picture!
  13. "Clutch Hot Warning"... but I'm stumped as to why?

    If you want to dive deep into the OEM clutch design, check out this thread I put together. https://www.jeepgladiatorforum.com/forum/threads/jt-jl-clutch-and-flywheel-explained-by-act.68758/ I will be adding some more information we learned recently in the coming days. Thanks MF Comics for the...
  14. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    I confirmed the alignment tools arrived today so everything is in stock. Our website should update either tonight or tomorrow, or you can call in the order.
  15. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    I just checked and we are currently waiting on more clutch alignment tools which are expected Monday. Everything else is on the shelf. edit: You beat me to it Kevin! Haha.
  16. Stop sale on manual transmission Gladiators (clutch assembly may overheat, causing a fire)

    I posted recent test results here: https://www.jeepgladiatorforum.com/forum/threads/jt-jl-clutch-and-flywheel-explained-by-act.68758/page-2#post-1135411 I plan to share other important test results after returning from a trip.

    Clutch Assist Spring Testing From a recent clutch installation on a Gladiator with 62K we were able to get more testing done and gain more data points to consider. First, we focused a lot on the pedal assembly and testing the assist spring. The illustration below explains how to interpret the...
  18. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    I don't know how much the truck's towing capacity will increase, but the actual clutch capacity for towing can be dramatically increased with an ACT clutch/flywheel. The added inertia makes it easier to take off or shift with less slipping, the higher clamp load makes torque capacity a...
  19. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    You need something to return the pedal to the top so the clutch fluid will equalize (self-adjust). I will post more on the assist spring soon in my tech thread. I am proposing a lighter spring that basically gives a bit more feel to the clutch. It's not the best answer, but it seems to improve...
  20. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    Agreed, they fail because the clutch is slipping. The cause for the clutch slipping isn't necessarily the clutch parts themselves. I am not saying it isn't a possibility, but it could be a few other things. Because the torque capacity seems adequate, it is more likely something preloading the...
