The Crankshaft Pulley Spacer 302/351W .909in Thick is an essential component for Ford small-block engine builders and performance enthusiasts working with classic muscle cars and street rods. This spacer sits between the crankshaft and the harmonic balancer, allowing you to fine-tune belt alignment and accommodate aftermarket accessories.
Designed to maintain the critical .909-inch thickness necessary for engine timing accuracy and pulley concentricity, this precision spacer ensures proper load distribution and prevents premature wear on belts and bearings. The robust design supports various configurations, optimizing pulley positioning for custom serpentine belt systems.
This spacer is ideal for 302 and 351W engine swaps, restorations requiring modern electrical systems, and high-performance build-ups. It is engineered to work seamlessly with OEM and aftermarket crankshaft pulleys, maintaining critical clearances between the harmonic balancer and engine block.
