This product was created due to the Weak Sealing Properties of the original OEM design.

The OEM design is prone to breaking and cracking even on moderate mileage units.
The OEM design has very poor sealing qualities and only has one set of sealing rings.
The aftermarket metal sealing rings dont work any better than the original scarf cut rings.

Sonnax has addressed these issues with Dual sealing rings and a Billet Anodized Aluminum piston.

There are a total of four sealing rings on this piston.
Two are Teflon rings that protect the piston to bore contact.
The other two are called "D" rings.
These give the piston much better sealing qualities than the original scarf cut rings.

The qualities of this dual seal approach and the integrity of the billet piston ;
make this Sonnax product an upgrade that is built to last.
