Tensioner Pulley Supercharger Pulley the same?

[robinsone]

Trying to order a replacement pulley for the belt tensioner (N/A) and I just want to make sure I don't order by mistake. Is the tensioner pulley the same as the supercharger pulley. It would appear from rockauto.com, but I want to be sure, are they the same pulley, dimensions, etc, thanks.

I believe its a 3.5 in pulley for the s/c belt line

# 3 is what you want.

this looks very wrong...

#3 & #8 on S/C side are regular thread, only alt. tensioner is reverse

#3 & #8 on S/C side are regular thread, only alt. tensioner is reverse

some bonnies and park ave's are reverse threads on the sc tentioner. most gp and regals are normal threads.

Gates, Dorman, or Dayco? Or does it even matter? thanks

I found Mexpulley on eBay. They use NTN bearings and are metal not plastic. About $15 dollars for ribbed they should have smooth also.

Bought the Dorman pulley, they are metal and have NTN bearings as well.
