I do not use them. I've seen even Super Sprags fail. If its a race trans and someones worried, they need a good drum. No other way around it. Even a LBA valve body equipped unit can fail a sprag, seen it.

No need for one unless the case is wore and won't hold the original.

I would venture to say our 727 gets as much or more abuse than anyone else on here. The car is usully driven twice a week (and not easily!), sees dragstrip action during the summer most every weekend I can and has over 5500 miles on this setup.

It is surprising how much power our relatively stock 727 has taken. I put good clutches and steels in it, a Cheetah fwd pattern manual valvebody and removed the governor.

I always shift to 2nd in the burnout box and have always torn it down for inspection after driveline failures.

This has been a topic quite often debated and the reality of the sprag or overrunning clutch is simple.Failure is a result of improper use or the result of component failure some where else.When failure occurs elsewhere and a sudden lockup occurs the overrunning clutch usually fails no matter how many rollers it contains,likewize improper use such as Ultra high RPM during a burnout or a high RPM flareup during a component failure usually will cause failure.If your stock overrunning is good there is no need to replace it,if it bad then any of the aftermarket replacement can be used.My take on supersprags is they are a excellent replacement if needed,but be cautious and operate the trans properly.Don't think that it will guard against stupity,it may just be that many little bullits flying out of the case.Dont think of a supersprag as invinciable.

Nothing is bulletproof. Sometimes you just do what you can to minimize or mitigate the weak links.

I'd read about people having sprag failures, front drum explosions, etc., and assumed it was something only "faster" cars needed to worry about. Then I was watching from the starting line when an 11.0 car's 727 puked on the hit, including the "big bang" from the stock front drum coming apart. The driver had to be helped out of the car by the track personnel because he was injured when the drum grenaded.

My junk was only as fast as that car was at that time, but my trans got pulled down and upgraded with a billet front drum, bolt-in sprag, and a few other things recommended by 440Jim at the time. I'm switching back to a LBA valve body now, too. It still won't be bulletproof, but it might be a little more stupidproof.

Parts don't have to be failed to be good candidates for replacement. Roller clutch parts that show wear are liable to hit the can. It's not like they are expensive or unobtainable.

And it's okay to decline work from someone who wants to nickle and dime you on everything. They will be the first to expect it to be fixed for free when it breaks, regardless how they broke it.


If the results don't match the theory, change the theory.

A customer who believes his opinion is superior to your is a problem in utero. If he wants to be the general contractor my responsibility is greatly reduced.
My old partner used to deal with this by raising the price substantially: if he refuses, he still thinks you do excellent work (more money always means better work to a squirrel), if he pays you have a cushion against complaints.

Still don't, despite indication of having been edited.

Maybe the OP has a multiple personality disorder.
