New Aftermarket FZR Sprag Clutch
Here is the pics of the clutch I am installing today.
It is built better than then stock unit for sure.
I don't think its going to solve the problems but hope it lasts 6-8 hours so I can finish out the year ridding. It has a different sound when spun than the stock clutch does.
It seems to be smoother??
The stock unit is on the right and the new one is on the left.
The new one uses a thicker better built single housing where the stock one uses two thinner weaker housings it appears.
If you want to get one Contact:
Part number is FE 8044 Z13
Cost will be closer to $300 just for the sprag.

Looks very promising. Many sprag bearings I have seen on heavier duty applications have all looked similar to your replacement piece. Thanks for your efforts, which ultimately will benefit us all...whether it works or not, I'm almost certain it will be 100x better. Any guesses on the torque applied on the sprag clutch? Looks like that sprag is rated for up to 315 ft-lb torque which seems to be more than sufficient. Anyhow, let us know how it works out.

This may be our answer, I have not yet blown my clutch but it will happen eventually.
Let us know how it works out.

Can that one be installed without having to alter anything on the charger or drive? Looks nice and definitely beefier!
I just sent an email to the local joint that we get alot of bearings and such through for work. Trying to see if they carry/can get GMN Bearing stuff or not.

I just got an email from Jerry, where a guy tested this last year and said it didn't last as long as a stock bearing.
I emailed him in hopes of getting his opinion of it and what happened in his testing.
I pulling mine apart now and will see what I hear.
Anyone have a turbo kit ready to go yet?

Well, I never heard from this person so I went ahead and installed the new clutch.
I don't want the hassle of returning it and getting a refund or even trying. I know that it has been tested by some people (2) but I just cant help but think that I might have better luck??
If it doesn't work it will take me 2 hours or so and I have a new stock clutch sitting here.
It just feels so much better when you spin it, the sound it makes is a better sound than the stock piece so I am going to give it a shot.
If nothing else everyone will know it works or it doesn't this way.
I will try and shot some video tomorrow if the sound that it makes is that much of a difference when idling and when its shut down.
