On the other hand, here's some pictures of the PowerTrax No-Slip unit that fragged in my rear after only about 20 miles of break-in use!

This was behind a mild 455 on rain-dampened streets after a slight wheelspin.
I hope this isn't indicative of the quality of the unit. I hope this was just a defective one. It was installed correctly and passed all tolerance and operation checks upon installation.
They're sending me another one. I have my fingers crossed.
