There is no reason you should be breaking DS in a 4.40 car! You either have bad shafts giving you the shaft or something else is wrong! Also note, I have seen too many DS get blamed for breaking when it was really the U-joint first!!! That said, the CV deal seams to be working good also. They will break also if not serviced. If you have a real fast four link dragster, consider using a DS can like what's required in TS cars. Dan Page make a nice setup that will contain a bust shaft! |

quoted for the TRUTH and FACTS! that said, I met Bret Goethe at the 2021 US Nationals Indy and we got talking. Bret wanted my business, came to my pit and measured my car for his driveshaft and it's been installed since March of 2022. |

Ditto. I have NEVER broken a shaft or U joint and I've been going fast in dragsters for 20 plus years. Mike Greene |

| Nor have I in over 3 decades in any of my cars, all with aluminum driveshafts, one near 60” long in a 3900 lb. car that had been 1.28 in 60 foot. |

| Bret nor MW offer it so there must be a reason. That said this does the job on a 8 second 3200+ lb. car |

And why do you think they did that?!!!! Not because they won't work!!!!! Also, another issue with short driveshafts that can cause issues, lack of adequate support at the trans end yoke support. Dan Page Race Cars makes a double roller bearing yoke support! This does a great job stabilization the driveshaft yoke! |

If true only because they now build a CV shaft which they make more $ on. My Undercover was built new with a MW Aluminum driveshaft and it went back to them for inspection and new U joints 3 years ago. |
