Dont forget PLUM BAD's foot....

Those pics are scarey .... but are you suggesting that a bolt-in-sprag from company A, B or C will prevent this ?

If so ...I will buy THREE of those sprags for 200$ each.

But ...until these companies will GUARANTEE that their sprag will not fail ...the only thing that I know-of that will prevent such a fireball-explosion .....

..... is an aluminum front drum.

those STOCK sprags worked well ...

DOC D no one is going to GUARANTEE ANYTHING against failure because once one happens to FAIL the drooling idiot buying based on MARKETING HYPE is going to SUE ...

NOTHING IS BULLETPROOF , the ONLY way to stop a front drum explosion is to REPLACE the STOCK FRONT DRUM ...

No replacement sprag will prevent this.


Only a LBA VB or a billet (steel or alum) drum will.

NOTHING IS BULLETPROOF , the ONLY way to stop a front drum explosion is to REPLACE the STOCK FRONT DRUM ...

... just what I said .... a couple of minutes ago.

Yeah ...isn't that special ?

Fight nice,group hug

I new it had to be a fluke

If someone can logically explain how a bolt in clutch(spragg) will prevent a trans explosion,then i will install them in all transmissions. When the clutch fails it is because the chain of events that brought on the failure could not be stopped soon enough.It's the drum failure that opens up the case and creates all the carnage.If the clutch breaks and the engine rpm is shut down immediately there is no explosion.

Wow this topic is like the discussion about Pinion Angles

First off, thanks for all of your input, as usual you have been a big help.
It may sound funny but I agree with all of you.
A little bit of history, this transmission does have an aluminum A&A Drum so that is not an issue.
But before we had the transmission, it belonged to Rod Gartin who was running it in a 23T with a 1000hp wedge in front of it. The car was going 7.40s with 1.0 60'. This all with the Stock sprag and a stock drum that had been lighten by Christian and Starky (for you Columbus boys)
So I believe that the stock sprag can handle the horse power. Heck if it wasn't for the pinion breaking we wouldn't be thinking twice about it.

But since it is apart and we have doubt in the back of our minds that the sprag could be hurt we don't want to take any chances, So we are going to put a new A&A Ultimate Sprag in along with a 5 pinion front planetary since we we're still running the stock planetary and it showed signs of going away on us.

Thanks again for all of your help, I really appreciate your help with this delema.

On another note....WHO WANTS TO TALK ABOUT PINION ANGLES
