{"product_id":"boost-valve-kit","title":"Boost Valve Kit","description":"\n\u003cp\u003eVehicles with listed GM transmissions may exhibit insufficient line rise in drive ranges, soft shifts and\/or burnt clutches. These problems may be caused by continuous oscillation of the boost valve within the boost sleeve, creating excessive wear and a path for EPC fluid pressure to leak to exhaust. Sonnax boost valve kit 104520-12K has upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control. The sleeve also has a slightly larger EPC feed orifice to provide quicker throttle response. A new pressure regulator valve outer spring is also included to replace weakened original springs and provides a modest 5 psi increase across the pressure curve.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eBoost sleeve is manufactured from highly wear-resistant billet aluminum to prevent wear\u003c\/li\u003e\n\u003cli\u003eLarger feed orifice provides quicker throttle response\u003c\/li\u003e\n\u003cli\u003eReplacement spring provides modest 5psi line pressure increase\u003c\/li\u003e\n\u003cli\u003eDrop-in Zip Valve™ parts install quickly and easily\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eValve\u003c\/li\u003e\n\u003cli\u003eSleeve\u003c\/li\u003e\n\u003cli\u003eSpring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eSymptoms:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLow line rise in Drive\u003c\/li\u003e\n\u003cli\u003eSoft shifts\u003c\/li\u003e\n\u003cli\u003eBurnt clutches\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e\n\u003cp\u003e\u003cstrong\u003eCause:\u003c\/strong\u003e\u003c\/p\u003e\nWear of the boost valve sleeve allows EPC fluid pressure escape to exhaust.\u003c\/div\u003e\n\u003cdiv class=\"col-4\"\u003e \u003c\/div\u003e\n\u003cdiv class=\"col-4 last\"\u003e\n\u003cp\u003e\u003cstrong\u003eCorrection:\u003c\/strong\u003e\u003c\/p\u003e\nSonnax drop-in boost valve kit has upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control.\u003c\/div\u003e\n\u003c\/div\u003e \u003c!-- suncoast-documents:start --\u003e\u003cdiv class=\"suncoast-product-documents\"\u003e\n\u003ch3 class=\"h6\"\u003eDocuments\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/183960.pdf?v=1793634977\" target=\"_blank\" rel=\"noopener\"\u003eInstructions\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\u003c!-- suncoast-documents:end --\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":49129556050139,"sku":"104520-12K","price":45.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198655213.jpg?v=1786546760","url":"https:\/\/suncoastperformance.com\/products\/boost-valve-kit","provider":"SunCoast Diesel","version":"1.0","type":"link"}
