Rear Pulley Rotor Spacer has 2¹⁄₄” I.D. and 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 align-
ment, 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 and designed to be used with 2000-up 
type wheel hubs.
