Bert Ballspline

[Rodneymod7]

Was wondering what everyone thinks about running a Bert ballspline in a 4 bar modified? I have herd good and bad. Aways looking for something better.

Only if your division allows carbon fiber drive shafts.

I've seen what happens when things go bad and your not left with much. the few gains you might think your getting aren't worth the risk. A local racer had a rear gear break and that transferred all the way up to the trany very quick the drive shafted did break but only after the main case of the bert blew apart the thing went off like a bomb. he was lucky it didn't come in threw the co ckpit. the chassis was also damaged from the tail of the trany betting around under the car.all it takes is for the rear wheels to be stopped instantly be it a gear failure or a hard hit from another car. I know a lot have been using them for years with no issues that's great glad to hear it.this is one story of many that's why some series mandate a carbon fiber drive shaft when running a ball spline.
