Pics of my Clutch Failure (SB)

I bought my truck with a 450hp single disk southbend clutch. I added a few power adders and the clutch started grinding (sounded liked fighting rats) after 25-30k miles. I drove 1500 miles with it like that until it locked up and i couldnt disengage the clutch. So i lookin into the southbend DD but didnt want to put that kind of money into this truck. I would rather put that money into my wheeling truck. So i got the 600 hp Ceramic Valair single disk.
I installed it today (1-17-10). After only 40 miles so far i love it! But i thought i would share the pics of my SB failure.

Right b4 i pulled the pressure plate


Once i took it off, parts just flew off in every direction






Now wait til you see the flywheel! The Springs were digging their way through!



Compared to the new one



Also, the Valair Kit installed very very well. Only issue was the lock washers for the pressure plate didnt work right.




Just for Laughs:

Ya, ive seen some strange failures. My friend spun the center out of his clutch. Surprisingly the input shaft had no damage.

Wow. Good carnage pics.

I put a dual disc SBC on my Stealth Twin Turbo and it held up great. Until I did an all wheel drive 5k rpm clutch dump and ended up spinning a rod bearing. But the clutch did its job, I guess.

Update:

So i have about 20k miles on my Valair Ceramic Clutch now. I LOVE IT. 4 of my friends are also running them now. I would recomend this setup if any of you are in need of a new clutch. Much cheaper than the other comparable clutches.

How does it do towing? Looking for a clutch right now and am wondering if I should get the ceramic or the kevlar/ceramic one.

I had the sbc con Fe, full feramic. and blew it apart. Called southbend and complained and they said they discontinued my clutch because it didn't work right. And that I could upgrade to a double disk for a nominal fee. It was almost the price of a new dd. I won't use sbc clutch.again.

What do you plan on towing?
If you tow daily, i might stay away from it. It def likes to grab. Its hard to creep around. When I am towing a skid steer, so like 12k combined weight, i use 4LO (i have manual hubs so its more like 2LO) to get around in tight spaces. It likes to buck. When i tow my off road truck (6-7k total) I dont have a problem. You will see yourself using 1st gear or "L" when towing any weight so your truck doesnt buck and jump.

I love the ceramic clutch though. It makes the truck a lot of fun to drive. It will take a beating. And if you slip it a little, it will really grab.

I have went full throttle with the DP all the way up on an on ramp towing 12k and it didnt slip.

Also, i have 50k on it now. Still feels like day 1.


Dont buy a SB...
