These standard harmonic balancer spacers are made of high quality aluminum and are the perfect way to adapt your balancer for your 5.0L application. All 1979-95 factory style 5.0L engines require the 81007 spacer for proper serpentine alignment.
Note: If you have a 5.0L engine running a belt driven blower, we recommend that you use our 81009 Steel Spacer instead of the 81007 aluminum one.
