Magnuson SC Coupler fail after 10k

Anyone have their coupler go bad shortly after bolting their SC on their truck (or any vehicle for the matter). Its not an expensive part, nor is it difficult to replace, but Im trying to sort out if I had something to do with its premature fail? (granted I haven't pulled the nose assembly out yet, but Im 90% certain its the coupler).

Also, anyone have any experience, or pros/cons to spring style coupler vs polyurethane coupler?

 

Edit* Seriously though, pictures help with clarification. Coupler is a pretty generic term.

 

Not really. There’s only one nose coupler in these Superchargers. But alas reference the photo, it’s the piece on the left.

 

Get the upgraded one from www.zzperformance.com

 

the replacement is on its way, I was asking around if anyone else had failed coupler that quickly?? After around 10k miles...theyre suppose to last around 100k if im not mistaken

 

How it is failed?

 

Isn't it supposed to break if something binds up stopping it from severely damaging it's self and sending debris into the motor?

 

Its become lose, there is some slack between the pulley and the coupler. Makes a rattling noise now, like little rocks are being turned inside the assembly
