Hello everyone, I just got a used lower pulley with cage in ebay. It is supposed to be a 4# Jdm lower pulley. Can any one show me pictures and if they know the diameter of the puller in inches. Just want to know if it is a real 4# jdm pulley. Thank you everyone!!

 

It should measure about 8.5 inches across behind the outer lip.

 

here are more sizes:

2# = 7.90"
3# = 8.17"
4# = 8.50"
5# = 8.75"
6# = 9.00"

 

I would guess the sizes are common with most vendors?
