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 having 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.
