Big Block Chevy Engines

These kits fit GM Mark IV, Gen V and Gen VI big block Chevy engines.

 


Harmonic Damper

Some factory Gen VI engines may have a different harmonic damper that must be changed. See picture below.

 

This is the factory Gen VI harmonic damper that must be changed. Notice there is no recess for the pulley boss to locate in.

   

 

This damper is representative of the vast majority of big block Chevy dampers found. Part #10216339 is available from GM. Always make sure your damper is the correct balance for your engine.

 


Additional Notes

  • Driver Series Kits are single 6 groove serpentine belt systems with spring tensioners
  • Driver Series Kits are designed for use with electric cooling fans. If you need to run a mechanical fan, contact us and we can make modifications to the waterpump pulley. Also, this kit uses a reverse rotation waterpump, so make sure the fan is a reverse rotation fan.
  • Our kits will not work with engines mounted with front motor mounts. Side motor mounts are recommended
