Torque limiting drive flanges?

[Revor]

While laying in a puddle of oil last night changing out a broken short side half shaft that I quite nicely sheared in two, I got to thinking about a product that I think I have seen for sale somewhere. I think I read about someone who was producing a drive flange that had a friction device in it that would slip if a designed torque load was exceeded thereby saving your half shafts from breaking.

I have been unable to find such a product on the net and am curious if anyone else has run into such a thing.

Thanks for your help!

GKN used to make them, but stopped many years ago. There were mixed feelings about them. They were only for 24 spline as well.

There are lots of options to improve the strength of the axles.

Hi, I beleive I saw them at drive products on 96th ave in port kells. They are special bolts & drive flange assembly ( I think they called them fuses ) that connected the drive line that would break and allow the drive line to rotate on its alignment shaft at a preselected torque. The driveline doesn't drop off when the fuses let go & The fuses are easily replaced.

While axles can break, never underestimate the contributing factor that your driving style can have on the problem.

It is cheaper just to get aftermarket half shafts...which are basically unbreakable.
