Porsche Clutch Rattler
When you have no space on the front of your crankshaft to fit a torsional vibration damper, you can fit a torsional vibration absorber on the rear of the crankshaft instead.
Vibration Free design and manufacture a large range of torsional vibration absorbers known as “Sterling Rattlers”; they have been very successful in solving issues where other options have failed and currently take the form of front mounted pulley style dampers or rear mounted flywheel dampers.
Now there is a new addition to the mix for Porsche boxer engines; a “Sterling Rattler” incorporated within the clutch pressure plate. This unique design overcame the lack of space available on the Porsche layout and subtly houses the Rattler within the specially made billet alloy clutch housing.
