Six-Star® Head gaskets are a multi-layer stainless steel head gasket engineered to insure years of longevity for your Subaru.

We believe so strongly in these gaskets that we exclusively use Six-Star® brand head gaskets on all of the phase1 and phase2 2.5 liter engines we repair at Smart Service.

We all know that a head gasket issue can be one of the biggest headaches you’ll ever run into on your Subaru. We only use Six-Star® gaskets at Smart Service when we perform a head gasket repair because we want it to be the final time you ever have to replace your head gaskets.

In our opinion, they are currently the best gasket available for the repair.

About Six-Star® Head Gaskets

The Viton rubber coating is one of Dupont’s high performance elastomers. In technical terms, Viton flouroelastomer rubber based material will easily handle temperatures from -40° to over 400ºF with the ability to withstand temperatures up to over 700°F for short periods.

The composition of these gaskets along with the interlocking embossments create unsurpassed sealing properties making Six-Star® Head Gaskets the ultimate choice for your all aluminum Subaru engine.

Why Choose Six-Star®?

The unique design and properties of the multi-layered stainless steel gasket combined with superior ability of the Viton coating to withstand heat, chemicals and corrosion, it may be the last head gasket replacement you’ll ever need for your Subaru engine. Not to mention, you’ll never need to use the Subaru Coolant Additive ever again on your engine.
