Use this crank pulley spacer with Ford Performance crank dampers (CJ Pony Parts # M6316C351, M6316A50 and M6316D302) to achieve proper belt alignment on your Mustang's 302 or 351W engine. This crankshaft pulley spacer is .950" thick and is precision machined for a perfect fit!

Features and Benefits:
- Premium Quality Component
- Important For Proper Belt Alignment
- For Ford Performance Crank Dampers
- Quality Steel Construction

This crank pulley spacer is important for your accessory drive. If you are using a Ford Performance crank damper listed above, this pulley spacer will make everything line up nicely.

Tech Tip: 1979 and earlier 351W engines with a 0.917" Ford Performance crank sprocket can use a Ford Performance Crankshaft Pulley Spacer (CJ Pony Parts # M8510A351) if 0.070" is machined from the rear of the damper hub. Early 3-bolt crank pulleys generally bolt directly to the damper (damper is drilled for 3- and 4-bolt patterns). However, sheave alignment should be checked and the pulley shimmed as necessary to correct any misalignment.
