Until now, the only way to make up for the rotator was to stack .300\" of shims under the spring. This was sloppy but also did not fit as well as these seat spacers. These will locate the spring with an outside step so the spring cannot \"walk\" around on the head.\t\t\t\t\u003cdiv class=\"product__accordion accordion\"\u003e\n\t\t\t\t\u003cdetails\u003e\n\t\t\t\t  \u003csummary aria-expanded=\"false\"\u003e\n\t\t\t\t\t\u003cdiv class=\"summary__title\"\u003e\u003ch2 class=\"h4 accordion__title\"\u003eAttributes\u003c\/h2\u003e\u003c\/div\u003e\n\u003cspan class=\"icon-caret\"\u003e\u003c\/span\u003e\t\t\t\t\t\n\t\t\t\t  \u003c\/summary\u003e\n\t\t\t\t  \u003cdiv class=\"accordion__content\"\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eCOMP Cams\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00036584089124\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eAmazon ASIN: \u003c\/b\u003eB000P5DE6C\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eC.A.R.B.
