if the sprag fails the front drumb goes either twice the engine rpms or it goes even higher than twice.that what makes them blow up.
the setting the sprag thing does not make sence with the low band applyed but then my feet are involved i tend to be extra carefull and if it only makes sence for a non rear band apply i can do it anyway.



2.2 times engine RPM... centrifugal force causes
the explosion... but the stock drum can take about
11,000 rpm before it comes apart so anything above
about 5200 rpm and its a problem(if the sprag fails)
I dont run a low band apply VB but I dont do stupid
stuff that will blow it
