C5 and C6 Crank Damper Upgrade (Harmonic Balancer Wobble Fix)

C5 and C6 Crank Damper Upgrade (Harmonic Balancer Wobble Fix)

Eliminate harmful crank damper wobble with this precision-engineered upgrade for C5 and C6 Corvettes. Factory harmonic balancers can develop excessive runout, causing vibration, noise, and potential engine damage. This direct replacement restores proper balance and concentricity, reducing stress on crankshaft bearings and extending engine life. Engineered for OEM fitment and performance. Stop the wobble—upgrade today.

We prefer to not install an OEM crank damper back on to the C5 and C6 corvette so you have 3 options that can fit your budget.

The package includes the following:

Your choice of Power Bond, ATI or Innovators west crank damper

Front main seal

New GM crank damper bolt (they are 1 time use and need to be replaced)

New engine belts

Alignment (we need to remove the engine cradle and steering shaft to perform this repair)
