You only want to do this once in the car’s life, so do it with the best parts!

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.

Subaru coolant conditioner is NOT recommended.

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.

Please make sure you enter your full VIN before you place your order so we can make sure you get the correct parts for your car.

At Smart Service (and Smart Quality Parts), we have been carrying and using the Six Star brand in our repair facility for over 15 years. Since the majority of our in-house technicians are Subaru factory trained we understand the benefit and need for correctly fitting and functioning replacement parts. The benefit of being an independent facility is that we are not required to use the Genuine Subaru stamped parts but unlike other independents, we didn’t want to use aftermarket parts just to cut costs and increase our margins.

We found Six Star in that search for the perfect balance between OEM quality and a more affordable price by cutting Subaru out as a middleman. We supplement with the Genuine Subaru parts where we feel that is needed or required if Six Star doesn’t manufacture a certain part, but we mostly use Six Star because more often than not the part is identical to what you would buy at the dealer.

The description below outlines the color and sticker system on the parts you may receive. Please know that 90%+ of the Six Star parts we carry are the Gold Star OEM designation and the Red Star options are just as good in our opinion (see our replacement oil filter for example, you can see it cut open next to a Genuine Subaru filter there is no difference at all).

We offer our own private Six Star label parts that identifies OEM parts with a gold star:

and alternative source parts with a red star:

Genuine = Exact part you would purchase at your Subaru dealer.
OEM = Original Equipment Manufacturer. The part was made by the exact same manufacturer that made the original part for your car. For example if you open a genuine Subaru wheel bearing you will find that the bearing is an NSK bearing. If you buy that same bearing OEM you’re getting the same part.
Alternative Source = These are parts that are manufactured by an indepedent aftermarket parts facility. Our alternative source parts are put through the rigors at Smart Service before we offer them online.

I really enjoyed the experience of buying from SmartQualityParts. I used these Six Star head gaskets from them on my ‘01 Forester and honestly, they were amazing. After rebuilding the motor, it never leaked again. This is really what this motor needs as these head gaskets do not have the graphite and won’t flake off. Really great parts with great customer service. Thank you!

My ’01 Forester SF was leaking due to overheating. After installing these Head Gaskets, the motor was bullet proof.
I would buy them again in a heart beat.

Put these in my 08 Outback around 10 years ago. No issues, no leaks, to this day. Around 100K miles. Getting some more for my latest Saaburu project.

After replacing the gasket, I gave it a good test drive about an hour. I can confidentially say the engine sounds healthier before doing the work.
