I've heard of a lot of rear axle failures that go along with sled pulling. Thought this little unit might help.

We've used this same stuff on dritrain test bench's for decades, its not new technology, in fact its just like a shear pin used in hundreds of applications. Danshsss, you don't break first then go smaller, you calculate first and save parts, its not all that dificult, the bolt will have a max shear load, or shear load failure rating, then compute that into the equation and find the right fuse, not that difficult, just expensive to have those plates welded into a driveshaft and balanced properly, you don't use those on high RPM compontents for a reason.

In sledpulling you want max shear strength so basically if thats what you make your fuse you could be replacing the fuse and the axle at the same time (hence kind of useless for us).
There has been many times when I thought I had actually broken an axle but it didnt break just grabbed a bit. Those times that fusable linke would have seperated and I would have lost a pull or worse yet the vehicle would have veered off to one side and risk injuring people or the truck getting hit by the sled.
