This kit speeds that process up with a quick-change housing top that swaps in seconds. The steel housing accepts AED's color-coded spring assortment, so a tuner can identify and change spring rates at the track or in the shop without fully disassembling the vacuum secondary housing each time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eComponent: Vacuum secondary housing top + spring assortment\u003c\/li\u003e\n\u003cli\u003eHousing material: Steel\u003c\/li\u003e\n\u003cli\u003eSprings: Color-coded for quick identification\u003c\/li\u003e\n\u003cli\u003eFitment: Holley carburetors with vacuum secondary\u003c\/li\u003e\n\u003cli\u003ePart Number: 5585\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat problem does this kit solve?\u003c\/h5\u003e\u003cp\u003eIt replaces the standard vacuum secondary housing top with a quick-change design, so spring rates can be swapped without fully disassembling the housing each time.\u003c\/p\u003e\u003ch5\u003eHow are the springs identified?\u003c\/h5\u003e\u003cp\u003eThe included springs are color-coded, making it easy to identify and select the correct spring rate during tuning.\u003c\/p\u003e\u003ch5\u003eWhat carburetors is this kit for?\u003c\/h5\u003e\u003cp\u003eThis kit is designed for Holley carburetors equipped with a vacuum secondary.\u003c\/p\u003e\u003ch5\u003eDoes the kit include a full spring assortment?\u003c\/h5\u003e\u003cp\u003eYes, the kit includes a quick-change housing along with a set of color-coded springs for tuning.\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"What problem does this kit solve?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It replaces the standard vacuum secondary housing top with a quick-change design, so spring rates can be swapped without fully disassembling the housing each time.\"}},{\"@type\":\"Question\",\"name\":\"How are the springs identified?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The included springs are color-coded, making it easy to identify and select the correct spring rate during tuning.\"}},{\"@type\":\"Question\",\"name\":\"What carburetors is this kit for?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"This kit is designed for Holley carburetors equipped with a vacuum secondary.\"}},{\"@type\":\"Question\",\"name\":\"Does the kit include a full spring assortment?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, the kit includes a quick-change housing along with a set of color-coded springs for tuning.\"}}]}\u003c\/script\u003e","brand":"Advanced Engine Design","offers":[{"title":"Default Title","offer_id":42987749343280,"sku":"BJLH_5585","price":35.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0586\/9548\/3440\/files\/AED5585.jpg?v=1777488459","url":"https:\/\/berryperformancesales.com\/products\/aed-quick-change-vacuum-secondary-tuning-kit-color-coded-springs-holley-5585","provider":"Berry Performance Sales","version":"1.0","type":"link"}
