I have a buddy that killed several of the high dollar pieces without too much abuse. We're not sure why, but he got tired of paying for them and replaced the last one with a stock part. It lasted for the rest of the time he owned the car.

I have a Ram Powergrip behind my 468.
It has some nice features and is SFI rated, for only about $300.
So far it has worked really well, but the car hasnt had sticky tires on it either.

That keeps the side yoke from being driven into the differential cross shaft and being worn down.
