The clutch springs determine the engagement RPM of the centrifugal clutch — the point at which the shoes engage the drum and drive is taken up. Spring rate selection directly affects how the kart pulls away and how the clutch behaves at low speeds, making this a key setup component on any dry clutch kart.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBlue springs are a specific rate — if you are replacing worn or broken springs, match the colour to your existing fitment to maintain the same engagement characteristics. If you are tuning engagement RPM for a different track layout, driver weight, or engine specification, spring colour selection is the adjustment to make.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSold in a pack of 10 — enough to service multiple clutches and keep workshop stock topped up.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFastline dry clutch\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eNoram 4000 series dry clutch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eColour:\u003c\/strong\u003e Blue\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePack size:\u003c\/strong\u003e 10 springs\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCompatible with:\u003c\/strong\u003e Biz (OEM ref: 110-0012)\u003c\/p\u003e","brand":"Rental Kart Parts","offers":[{"title":"Default Title","offer_id":57661613605247,"sku":"KPDCCLSB","price":24.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/0772\/6975\/files\/64d083_93afc0a44a0a4a8fb62f44f445a710ab_mv2_1.webp?v=1780408304","url":"https:\/\/rentalkartparts.com\/products\/dry-clutch-spring-blue-steel","provider":"Rental Kart Parts","version":"1.0","type":"link"}
