How much torque should you put on the Hermonic Balancer Bolt?
Silas R May 23, 2016

Is it made in the USA?

Can a bad harmonic balancer cause a new oil seal to fail rt away ?
Donnie L July 27, 2017
This is a possibility. If the harmonic balancer will vibrate a little and move more loosely which could affect the seal.
Alex P July 28, 2017
Will this fit a 04 silverado 5.3l?
Treyvonne S November 4, 2017
Does it come with a new key way?
Wayne W July 23, 2018
This is only the harmonic balancer. It does not include anything else.
Christa R July 23, 2018
This type of Balancer does not use a key way. Its a press fit and you must use a new bolt and follow the torque specs to the letter. Bill N
