I've had this clutch in less than 8000 miles. Never had a slippage problem till about two weeks ago. Clutch was broken in properly. Only had bosch 190s in during break in with a stock fuel pump that was new.

Now I'm running all of what's listed in my sig below

Rear main seal is ready sleeved and resealed during install so oil isn't a problem and I double checked by peeking up in there. If I go over 35 psi it just slips like crazy. And can't even go past 25 in 4th gear or 5th

I've never abused this clutch either in fear of exploding the getrag.
Never slipped it other than the usual taking out.

It's been babied enough that I use first gear every time I take out. Never towed more than a cgvwr of 15000ish

Problem is I'm thinking since I've had it in over a year and a Half maybe two years that there's nothing sound bend is going to do.

I know I'm not over the 475hp or 1000ft lbs of torque for sure with a VE truck.

Probably going to go with the getrag street dual disc they have but what I'm wondering is how is that clutch going to perform if I ever decided to do a truck pull or a boosted launch now that these days I'm getting power hungry

Anyone have any input on southbends customer service or is that just something I should call and find out.



for those of you who do not know what clutch this is

Dyna Max Clutch Kit 13125-OFEK
This Dyna Max kit features a variation from organic to organic and feramic or all feramic linings with marcelled fins. The pressure plate is modified for higher plate load and smoothness of engagement. This clutch was designed to cure premature disk failure due to high horse power and heavy hauling in the 5 speed and early 6 speed non-ETH 12 1/4" clutches. We have taken the 13" ETH clutch and modified it to accept the 1 1/4" input shaft. By doing this, it enabled us to offer a disk center that is 2-3 times larger and stronger than can be provided in the 12 1/4" clutch kits. This kit comes with a flywheel, re-drilled and refaced to accept the larger clutch and is rated to handle up to 475 horsepower & 1000 ft. lbs. of torque. Years 1988-2004 5 speed & 6 speed non-ETH.

 

I would call them, at the least they may want to see pictures when you have the clutch out.

I run the valair dual organic disc and it handles 40psi of boost and 12k behind me without sweating.

 

I have heard good things about South Bends customer service.
I have also had great luck running their clutches in several Cummins powered trucks.

 

X3 it never hurts to ask.

 

I'll be pulling the clutch as soon as my south bend dual disc clutch arrives. I'll post some pictures up here and maybe you guys will have some insight on what may have happened
