More Info:
True conical valve springs are not a new concept and are industry proven to provide several key advantages over traditional spring designs. A major advantage of conical springs vs. traditional cylindrical or beehive springs is the damping and removal of valvetrain harmonics.
Of the three designs, conical springs are the front runners in valvetrain harmonic stability. Utilizing a varying coil diameter as well as coil spacing, a conical spring acts as a natural harmonic damper in the transfer of valvetrain shock. This translates to less stress, less wear, and a longer life of the included components.
This level of protection is needed in today’s engines being pushed to their physical and mechanical limits by aftermarket modifications. Every GSC conical spring offers a super finished surface treatment to go along with the patented, multi-step heat treatment process. The finished product is an extremely reliable, high-performance spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures.

Must have for rosacea sensitive skin!
Style: Tolerance Control Soothing Skin Recovery Cream
I have fair, sensitive skin & since being in peri-menopause I suddenly have rosacea. This cream is SO gentle on the skin but so instantly calming. It hydrates so well & a little goes a long way. I will be buying this over & over from now on!

Great for Sensitive Skin
Style: Tolerance Control Soothing Skin Recovery Cream
I have very sensitive skin and have tried everything to try and prevent rosacea flairs. I recently came across this brand and I absolutely love this recover cream. I consider this now the holy Grail for Rosacea and sensitive skin. It makes my skin feel hydrated and non-reactive. It is soothing and I just cannot get enough of it. It is pricy but it is worth it to not have my face constantly feeling like its burning or irritated.

Great product for sensitive skin
Style: Tolerance Control Soothing Skin Recovery Cream
I have sensitive skin that is constantly getting irritated by moisturizers/seemingly simple skin care products. I read a few blogs/articles/reviews on different products others have tried for similar issues and this one came up, so I decided to give it a try. It’s nice and light and goes on smoothly. Skin feels moisturized and does not get irritated, so that’s a win! The only reason I took off 1 star is it leaves my skin a bit oily for my liking, but that could just be my skin.
