Centerforce Clutch Updates.

[word302]

Are there any tuners that get rid of the flash that pulls torque to save the clutch?

There’s no reason to disable this function. It puts your Jeep into limp mode if the clutch gets extremely hot. Doesn’t do anything under normal circumstances.

For visualization sake, I'm assuming that it's a variation of this...

I love the idea of a hydraulic throw-out bearing. I'm wondering if they are considering offering it as an upgrade to the stock slave cylinder arrangement. When I do my clutch, it will be with a CFII and I'd spring for this as an upgrade.

Throw out bearings/slave cylinders are very specific to the application. The front of the transmission where the input shaft is needs to have threaded mounting holes to attach this style slave. This is what I have on my Dakota but it was swapped to a Viper T56. The entire hydraulic system is now Viper specific. The stock Jeep TO bearing uses that yoke shaped lever and does not use threaded mounting holes in the face of the transmission. There might be an adapter plate included, not sure. Mine just uses a spacer to get the distance to the pressure plate correct but it uses the same bolts that the TO bearing does. I can't tell a huge difference between the shaft mounted slave cylinder vs the one mounted outside the tranny but this setup uses a pilot bearing in the crank unlike the Jeep and was not subject to this kind of clutch failure.

Copy. It just seems easy to stall compared to other vehicles I've driven, especially in reverse.

The included heavy flywheel will help with that.

So to those with more useful knowledge of the OEM clutch and/or CF II, this new TO bearing/slave cylinder is not necessary, even if one is made specific to our JL's??? I have the CF II, just want to get everything right, one and done, once I have the install done...I hate to mess with my clutch which is performing fine but the threat and better clutch performance pushes me to go ahead with it...won';t be driving it much this winter so might do install in spring...

Truthfully, the way that the factory and current centerforce kit works is THE standard way that manual transmissions have worked forever. They just have an external slave cylinder that pushes on a lever that is slotted on to the throw-out bearing. I would not worry about installing the kit as is.

Thanks I shall heed your advice, wasn't looking forward to spending another $4-500 on the clutch crap. Already pretty annoyed its an issue in the first place...

So strange why anyone would want to remove a safety feature like this.

The thought of "limiting" potential engine output on rare occasions and for a short amount of time is apparently so vile and repulsive that some people would rather risk a potential catastrophic explosion/fire?

How about the redline rev limiter folks? There is more power to gain at those higher RPMs. How DARE Jeep try to stop that with their nanny ECU!?! How do I program that out? /s/

Not having a pilot bearing and input shaft interface with the crank is a terrible setup. That's different than any other manual setup I've seen. Even with a bronze bushing for the pilot would be a huge improvement.

Why would anyone want to increase the size of their stock tires and alter the way Jeep designed the vehicle? Why would anyone want to modify their engine or put on a lift kit? Why, oh why?

The Jeep that burned to the ground event happened AFTER the recall.

Oh, I completly agree about that. To my knowledge, this is what Centerforce has fixed with their latest clutch.

I was just referring to the throw-out bearing and slave cylinder design that cutterone was worried about.

No the Jeep that burnt to the ground was before the recall that added limp mode. There have been 3 or 4 recalls on the clutch since the JLs inception. Your comparison of tires to the limp mode safety feature is ridiculous.

So just to be clear, I'll be well served with only installing the newest CF II kit I am in possession of...

From what I have read about, yes. ... But, I should clarify, that I have no more information than what has been posted across this forum and is on their website.

Does anyone with more information care to comment?

Call Centerforce, ask them!
