Isolate harmonics before they can destroy your engine.
FACT: harmonics CAN destroy these motors despite their ideal 'inline six' balance. Our engineers teamed up with the harmonic pros at ATI to design the only S54 damper racers will need. Simply fitting engines with the VAC damper solves harmonic issues and restores confidence in the powertrain. We have many professional drivers that are pushing 9,500-10,000 rpm running our S54 Harmonic Damper, working flawlessly with or without our S54 Stroker Kit!
Included in the Kit:
WARNING: ***Will NOT work with a factory damper pulley*** The VAC Underdrive Power Pulley is needed for this damper to function properly.
When used with our included VAC Crank Pulley, this is a direct bolt on solution. Available in:
_ Standard Diameter (May be used in conjunction with Underdriven accessories)
_ Overdrive (May be used with Supercharged Applications)
_ Underdrive Version (Not recommended for use with Underdrive Water Pump Pulley. If used, this may slow down circulation too much and affect cooling)
Also, configurations available for use with our dry sump kits. This damper has a 7" outer diameter and it includes OEM style timing alignment tabs.
