It uses a single adjustable valving design that softens or stiffens the overall ride with one knob, which suits street driving. The threaded body and included hardware kit allow quick and easy ride height adjustment, and a 2.5 inch spring of the appropriate length and rate completes the setup. Each Proma Star shock is made in the USA and dyno tested, and is covered by a limited lifetime warranty when registered before installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Proma Star coil-over shock\u003c\/li\u003e\n\u003cli\u003eAdjustment: single adjustable\u003c\/li\u003e\n\u003cli\u003eSpring: accepts 2.5 inch diameter spring (sold separately)\u003c\/li\u003e\n\u003cli\u003eCompressed height: 9-1\/2 in\u003c\/li\u003e\n\u003cli\u003eExtended height: 12-3\/4 in\u003c\/li\u003e\n\u003cli\u003eMounting: poly bushing top and poly bushing bottom\u003c\/li\u003e\n\u003cli\u003eMade in the USA, dyno tested\u003c\/li\u003e\n\u003cli\u003eLimited lifetime warranty with registration\u003c\/li\u003e\n\u003cli\u003ePart number: DS304\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles do QA1 Proma Star coil-over shocks fit?\u003c\/h5\u003e\u003cp\u003eThey are universal coil-over shocks for a wide range of vehicles and custom chassis or suspension builds, rather than a direct fit part.\u003c\/p\u003e\u003ch5\u003eIs the DS304 single or double adjustable?\u003c\/h5\u003e\u003cp\u003eThe DS304 is single adjustable, using one knob to soften or stiffen the overall ride.\u003c\/p\u003e\u003ch5\u003eWhat are the compressed and extended heights of the DS304?\u003c\/h5\u003e\u003cp\u003eThe DS304 has a compressed height of 9-1\/2 inches and an extended height of 12-3\/4 inches.\u003c\/p\u003e\u003ch5\u003eWhat spring does the Proma Star shock use?\u003c\/h5\u003e\u003cp\u003eIt accepts a 2.5 inch diameter spring of the appropriate length and rate, which is sold separately.\u003c\/p\u003e\u003ch5\u003eWhat mounting does the DS304 use?\u003c\/h5\u003e\u003cp\u003eIt uses a poly bushing mount on both ends.\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What vehicles do QA1 Proma Star coil-over shocks fit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"They are universal coil-over shocks for a wide range of vehicles and custom chassis or suspension builds, rather than a direct fit part.\"}}, {\"@type\": \"Question\", \"name\": \"Is the DS304 single or double adjustable?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The DS304 is single adjustable, using one knob to soften or stiffen the overall ride.\"}}, {\"@type\": \"Question\", \"name\": \"What are the compressed and extended heights of the DS304?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The DS304 has a compressed height of 9-1\/2 inches and an extended height of 12-3\/4 inches.\"}}, {\"@type\": \"Question\", \"name\": \"What spring does the Proma Star shock use?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It accepts a 2.5 inch diameter spring of the appropriate length and rate, which is sold separately.\"}}, {\"@type\": \"Question\", \"name\": \"What mounting does the DS304 use?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It uses a poly bushing mount on both ends.\"}}]}\u003c\/script\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":42664481423408,"sku":"BJGM_DS304","price":254.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0586\/9548\/3440\/files\/2a29efca95bee.jpg?v=1766455699","url":"https:\/\/berryperformancesales.com\/products\/qa1-proma-star-single-adjustable-coil-over-shock-bjgm-ds304","provider":"Berry Performance Sales","version":"1.0","type":"link"}
