ASP Underdrive pulley for 3.4 DOHC


Recommended Posts

Posted

So I bought this pulley from a known community member on facebook (not a scammer), and I installed it, and when I started the engine it instantly shredded the belt.  

 

I assumed I did something wrong but on closer inspection the pulley is way too "shallow".  Did I get a pulley for the wrong engine?  I compared the stock pulley on my 3.4 to my spare engines and they are all deep (like the black one in the picture).

The directions do not mention any spacer or anything.
