Thread: Gun Drilled Output shaft

Better safe than sorry? I dont have any experience with the part so i cant vote.

I talked to Dave at one point. Another Bonneville friend Tommy Glover had one shatter on him.

Of all the big builds I've seen, worked on and dealt with...not one had a problem with the stock output shaft. I abused the crap out of mine and it shows no signs of any issues at all.

Um?? Ok I've tried to search Gun Drilled output shaft. Couldn't find anything thing on GPF. Not too many people know what a gun drill is. (in my experience anyway). But the only thing a gundrill does is put a long hole in a part. THAT'S IT. nothing special. So does removing material from a shaft make it stronger???? Link to this gun drilled shaft??? I can have an Engineer buddy take a look...

ZZ Performance

Gun drilling gives us a 20% reduction in weight from the stock unit. Lighter components make your car faster and your transmission more reliable.

ZZP output shafts are engineered so well that they come with a life time guarantee against breakage. The shaft can be replaced with the transmission still in the car, this means 1 hour install times!

Funny thing is when one breaks the typical response on this "lifetime warranty" is that it was shocked by a burnout and best of luck.

no not worth it, stock is fine

Removing material on the I'd removes weight, it does not add strength. Removing material on I'd makes the part slightly weaker.

Id rather break a stock one that is easily removable then break an aftermarket one that explodes.
