The Stepped Washer For 31030 Pulley from ALLSTAR PERFORMANCE is a precision steel component designed specifically for use in pulley assemblies within high-performance engine building. This washer is essential for ensuring proper alignment and load distribution in crank mandrel applications, making it a critical component for builders and engine shops focused on automotive and racing environments.
Manufactured from durable steel with a black oxide finish, the stepped washer is engineered to seat firmly on crank mandrels, accommodating the specific bore geometry of compatible pulleys. This design helps prevent lateral shift during engine operation, thereby maintaining concentricity and reducing wear on components. The black oxide coating also provides corrosion resistance and minimizes galling when tightened against other steel surfaces.
Builders installing the ALL 31030 pulley or compatible crank-driven accessories on small-block and mid-size engines will find this washer indispensable. Proper installation ensures balanced pulley operation, reduces vibration, and protects bearing surfaces from axial loading. This washer is a reliable choice for both street and racing applications, contributing to the longevity and performance of engine components.
