does anyone know what the stock pulley(press on pulley) size is for the cobalt supercharged?
i think its a 3.3"

i have a friend that wants to put it on his GTP...
and if the shafts are the size size?
i would think they are the same, we looked at them and they looked the same but i dont want to take it apart not knowing.

thanks

 

i hope you noticed his belt has more ribs than ours also

 

no i just glanced at it but thanks so i guess gm was smart enough to make them diff. ....

 

i think they have 3 more ribs than us or 2 more of something, i forget

 

to answer the original question though, stock pulley size is a 3.34"

 

this pulley will work on the gtp...
just to let anyone know
