Kerma Performance Crankshaft Damper for Mk4-Mk7, Audi A3 TDI

What It Is
A performance crankshaft damper for VW and Audi TDI engines, designed and made in the USA, built to replace the factory damper with a design that better controls crankshaft vibration.

Why It's Worth Upgrading

• Eliminates torsional crankshaft vibrations that the stock damper doesn't fully control
• Reduces or eliminates clutch chatter and shudder
• Can recover up to 5% more usable power, since some of that power is otherwise lost to vibration through the OEM damper
• Uses elastomer technology with a rebuildable insert, effectively 2 dampers in 1
• Carries an SFI 18.1 safety rating
• Includes new crankshaft bolts

Why Elastomer Over Viscous Fluid
This damper uses a vulcanized rubber elastomer design rather than a viscous fluid damper. Fluid-filled dampers can harden over time or develop leaks, while the elastomer design holds up more consistently over the long term.

Fitment
2013-2016 Volkswagen Beetle, Golf, Golf Sportwagen, Jetta, and Jetta Sportwagen, and 2013-2016 Audi A3 TDI.

Common Questions

How much power will this actually add?
Up to 5%, since that's roughly how much power the stock damper design loses to vibration. Results depend on your specific car and setup.

Is this a rebuildable part, or does it need full replacement over time?
It has a rebuildable insert, so it doesn't need to be replaced outright the way a worn-out stock damper typically does.

Why is this better than a viscous fluid damper?
Fluid-filled dampers can harden or leak over time, while this elastomer design tends to hold up more reliably long term.

Are new bolts included?
Yes, new crankshaft bolts are included with the damper.
