Anyone having issues with TRD Supercharger pulley's?

I am having issues with Toyota extended warranty dept denying warranty replacement of defective TRD Supercharger pulleys. SC is covered for 7/100,000 under platinum warranty. Any info please?

 

What's wrong with it? Stock pulley or aftermarket pulley?

 

What he said^^^.

Also, did you buy the truck used with the s/c on it, or did you have the s/c installed?

Since you said "pulleys", which one or ones?

 

I have the TRD Supercharger and running the URD 2.85 pulley and both seem to be working just fine for the last 100k miles.

 

The supercharger is covered by the Standard manufacturer warranty(3 yr/36,000 miles) and only IF installed by a Toyota dealer.
Extended warranty only covers FACTORY INSTALLED parts. You should never get an an extended warranty for a modified vehicle, it's a waste of money.
Pulleys would be wear items anyway.
