{"product_id":"s-s-compression-release-kit-for-s-s-heads","title":"S\u0026S, compression release kit for S\u0026S heads","description":"Electrically operated. Large displacement \/ high compression motors with S\u0026amp;S cylinder heads can sometimes be troublesome to start. These electrical operated compression release valves are opened by two separate solenoids; when the starter button is activated. When starter button is released the release valves close. 9\/16-20 threaded. Note 1: Will only work with S\u0026amp;S style heads that are S\u0026amp;S machined to be run with compression releases. OEM heads will not have enough material in critical areas to allow machining. Note 2: All 89cc S\u0026amp;S TC cylinder heads are machined at the S\u0026amp;S factory. Machining on the 79cc S\u0026amp;S TC heads is optional. Note 3: Will only work with S\u0026amp;S style rocker covers ''with the central hole'' which provides the necessary clearance for the solenoids. Note 4: For replacement parts see 531408 (compression release assembly); 531407 (wiring harness) and 531422 (silicone solenoid caps).\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e All S\u0026amp;S cylinder heads machined by S\u0026amp;S to accept compression releases (NU)\u003c\/p\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":54307764306247,"sku":"915195","price":563.26,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/7812\/0519\/files\/915195k.jpg?v=1784474503","url":"https:\/\/www.chopperessentials.com\/products\/s-s-compression-release-kit-for-s-s-heads","provider":"Chopper Essentials Co.","version":"1.0","type":"link"}
