These problems can be caused by the reciprocating boost valve wearing the inside diameter of the boost sleeve. When this occurs, oil that enters the modulated throttle valve orifice leaks past the boost valve and exhausts through the Reverse orifice or to the sump, resulting in poor line rise. Also, Reverse oil can exhaust both to the sump and back through the modulated TV orifice. The Sonnax boost valve kit 34910-05K eliminates the above problems.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eBoost valve and sleeve are manufactured from high-quality steel\u003c\/li\u003e\n\u003cli\u003eUses the same valve spool diameters as OE to regain factory shifts\u003c\/li\u003e\n\u003cli\u003eDrop-in Zip Valve\u003csup\u003e™\u003c\/sup\u003e 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\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\u003c\/li\u003e\n\u003cli\u003e1-2 Soft\u003c\/li\u003e\n\u003cli\u003e2-3 Soft\u003c\/li\u003e\n\u003cli\u003eDelayed Reverse\u003c\/li\u003e\n\u003cli\u003eReverse shudder\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 sleeve I.D. due to continuous oscillation of the boost valve.\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\nFactory-style Sonnax drop-in boost valve kit restores hydraulic integrity with closely toleranced parts.\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\/184373.pdf?v=1793635346\" 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":49129573548251,"sku":"34910-05K","price":78.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198656637.jpg?v=1786547259","url":"https:\/\/suncoastperformance.com\/products\/boost-valve-kit-factory-style-no-o-rings","provider":"SunCoast Diesel","version":"1.0","type":"link"}
