Do I have to get a new belt if I'm going from 2.8 pulley to stock pulley...or are they the same size..reason for switching back to stock pulley is bc previous owner put a 2.8 on without tune and injectors...and I dont want my engine blowing up lol.

 

Yes you would need the oem belt length. For a 2.8 the belt would be shorter.

 

Thank you!
