A micro-peening process is used to increase durability and longevity of the spring, which means you can push harder for longer. In addition, the added heat treatment reduces load loss during operation. Some springs in the series are also nitrided for racers who are looking to increase lift capacity and number of cycles over the life of a spring. The Signature Series Valve Springs are perfect for extreme stress applications such as professional drag and oval track racing.\u003cbr\u003e\u003cbr\u003e\u003ch5\u003eSpecifications:\u003c\/h5\u003e\u003cbr\u003e\u003ctable class=\"descr-table\" border=\"0\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalifornia Proposition 65\u003c\/td\u003e\n\u003ctd\u003eWARNING: This product contains a chemical known to the State of California to cause cancer, birth defects or other reproductive harm.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoil Bind Height\u003c\/td\u003e\n\u003ctd\u003e1.081\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASC\u003c\/td\u003e\n\u003ctd\u003eSee 74620-1 for single spring.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DEF\u003c\/td\u003e\n\u003ctd\u003eEngine Valve Spring Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DES\u003c\/td\u003e\n\u003ctd\u003eSignature Series Dual Spring 1.514\" O.D.; 1.850\" Installed Height; 1 Spring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DES\u003c\/td\u003e\n\u003ctd\u003eSignature Series Dual Springs 1.514\" O.D.; 1.850\" Installed Height; 16 Springs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_EXT\u003c\/td\u003e\n\u003ctd\u003eThese Lunati Signature Series Double Valve Springs feature a 1.514\" O.D.; with an installed height of 1.850\".
