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 RPM's, use more aggressive cam profiles, and turn up higher boost pressures.\u003c\/p\u003e\n","brand":"GSC Power Division","offers":[{"title":"Default Title","offer_id":67903008670016,"sku":"GSC5073","price":1225.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/1152\/0064\/files\/5073-2.jpg?v=1793263292"},{"product_id":"gsc-37mm-1mm-intake-valve-single-gsc2014-01","title":"GSC 37mm (+1mm) Intake Valve SINGLE GSC2014-01","description":"\u003cp\u003e\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GSC-37mm-1mm-Intake-Valve-Set-of-8-Subaru-EJ20\/EJ25-2014-8\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003c\/p\u003e  \u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eNote: Single Valve Only. 8 Required for full engine build.\u003c\/strong\u003e\u003c\/p\u003e  \u003cp style=\"text-align: justify;\"\u003eWhen creating our new valve line we set out to create the best performance, longest lasting valves available to the aftermarket. Using advanced 3D design and simulation software, we have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific applications to make sure we have the highest flowing valve head available on the market today. With the materials used, we have less valve distortion at the face than any of the tested designs. Less distortion allows for better sealing under extreme conditions and more consistent performance throughout the life of the valve.

High RPM and High Boost levels are not a problem on these kits. 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.
