From upright outline shapes for quick turn and tight pocket surfing, to more raked templates with added sweep and rake for powerful hold, there’s a combination to suit every surfboard and every style. Many models feature Performance Glass and Performance Glass PG construction, offering excellent stiffness, clean response, and the kind of control you need when you really want to push hard through turns. This premium material and thoughtful construction help reduce drag while increasing stability, precision, and overall performance.\u003c\/p\u003e\n\u003cp\u003eCompared to newer FCS II fins and the tool-free FCS II system, the classic FCS system remains a favourite among surfers who like the familiar feel and added security of tabs and screws. It’s an ideal choice for older boards, backup sets, or anyone who prefers the traditional fin system connection. With different size options, flex pattern variations, and templates suited to smaller, mid, or more powerful conditions, choosing the right fins can completely transform how your board feels under your feet, adding greater speed, smoother release, and more confident drive through every turn. Use the filter tools on our site to find the perfect set for your surfing style, board, and local conditions. Every product page is packed with info to help your search, so you know exactly which template, base, and flex you’re getting. We deliver fast, making it easier than ever to upgrade your surf setup with high-quality FCS fins from a leading name in surf hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n                    \u003c\/div\u003e\n                    \u003cbutton class=\"content-truncator__button link tap-target--small underlined-link t3\" style=\"display: inline-block;\"\u003e\n                      Show more\n                    \u003c\/button\u003e\n                  \u003c\/content-truncator\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/surfboard-fins\" class=\"t4 font-bold button button--primary button-with-icon button-with-icon--left\" style=\"color:#ffffff\"\u003eView all Fins\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" focusable=\"false\" class=\"icon icon-arrow icon-arrow-left\" viewbox=\"0 0 512 512\"\u003e\n  \u003cpath fill=\"none\" stroke=\"currentColor\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M268 112l144 144-144 144M392 256H100\" class=\"stroke-width-standard\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"fcs-g5-thruster-fins-in-black","title":"FCS G5 Thruster Fins in Black","description":"\u003cp\u003eFCS G5 Thruster Surfboard Fins in Black\u003c\/p\u003e\r\n\u003cp\u003eFCS Thruster \/ Tri fins for FCS double tab system.\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eMedium Size Fin\u003c\/li\u003e\r\n\u003cli\u003eComposite material \u003c\/li\u003e\r\n\u003cli\u003eGreat all round fin template \u003c\/li\u003e\r\n\u003cli\u003eGenuine FCS product\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"FCS Fins","offers":[{"title":"Default Title","offer_id":54487876206918,"sku":"110310400R","price":29.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/2675\/4630\/files\/fcs_g5_thruster_fins.png?v=1754664002"},{"product_id":"fcs-arc-pc-thruster-fins-large","title":"FCS ARC PC Thruster Fins - Large","description":"\u003ch2\u003eFCS Double Tab ARC Performance Core Surfboard Thruster Fins - Large \u003c\/h2\u003e\r\n\u003cp\u003eDesigned for fast, controlled on-rail surfing. \u003c\/p\u003e\r\n\u003cp\u003eThe raked template porduces exceptional speed and drive, allowing the rider to push hard through their turns.
