New Harmonic Balancers
New Damper Doctor harmonic balancers are made to factory specifications, with all new components.  You do not need to worry about replacing or repairing old harmonic balancers that may have cracked keyways, worn hubs, or striped bolt holes.  Also, new dampers do not have a core charge included in the price.  These balancers use neoprene rubber that is closer to the OEM model.  New harmonic balancers carry a 1 year limited warranty.

Rebuilt Harmonic Balancers
Rebuilt harmonic balancers have a refundable core value.  All rebuilt harmonic balancers are first disassembled and cleaned.  The parts are then inspected for defects, including stripped bolt holes and worn or cracked keyways and hubs.  Harmonic balancers are then prepared for assembly.  Timing marks are set to the factory specification by using a laser aligning process.  After the timing marks are set, the harmonic balancers are then injected with a high-temperature, high-strength silicone rubber that is then platinum cured for a extremely strong hold.  The new silicone rubber is capable of withstanding temperature in excess of 450 degrees, and will hold up against pressures as high as 770 psi.  Rebuilt harmonic balancers carry a 3 year limited warranty.
