Rear Pulley Rotor Spacer is ideal to get belt pulleys or chain 
sprockets in line. These spacers can also be used as a disc spacer. 
Spacer can be machined down to the next size under without hav-
ing to worry about the spigot alignment, when you machine the face 
of the spacer down to the desired thickness on spacers with spigot. 
Spacers are drilled for use with 7/16” bolts. I.D. is 21/16” for 1980-99 
and 21/4” for 2000-up.
