What size is the stock pulley. I measured mine it was almost 8 inchs form side to side. It is more like 7 & 3/4. Josh (blown5pnt4) thinks that I might have a 2lb pulley on my truck. so what pulley do I have on my truck.

 

ID put money on it being a 2lb pulley.

 

here are some lower pulley diameters I found from a search:


2# = 7.90"
3# = 8.17"
4# = 8.50"
5# = 8.75"
6# = 9.00"
also if it's uncaged it's definitely aftermarket.

they vary a little by manufacturer

 

Hey Jay, I just went outside with the flashlight and tapemeasure and the 2# on the truck right now measures right at about 8" when going straight through the center nut. I think you got a 2#er there man.

cool that works for me. So now I know the truck has a 2lb pulley, Borla cat back and a drop in K&N filter. I also just did the boost by pass mod and the pcv mod. LOL it's starting to become an addiction very slowly.
