Crankshaft Pulley Spacer
An automotive crankshaft pulley spacer is a small metal component that is designed to fit between the crankshaft pulley and the harmonic balancer. The purpose of the spacer is to adjust the distance between the crankshaft pulley and the harmonic balancer, allowing for the correct belt alignment to be achieved with the other pulleys. In some cases, the use of an aftermarket crankshaft pulley or harmonic balancer may result in a distance discrepancy, which can cause belt slippage, premature belt wear, or even engine damage. By adding a crankshaft pulley spacer, the correct distance can be achieved preventing these issues.

When selecting a crankshaft pulley spacer, first confirm the year, make, and engine size. Next, determine how thick the crank pulley spacer needs to be to provide proper alignment. Finally, from the remaining compatible options, choose the spacer that best meets your application and budget needs.

These vendors include KRC, Speedmaster, Ford Performance, Eddie Motorsports, March Performance, and others.
