Under trade secret Radial-Densification (RAD), the physical properties of Tool Room springs are optimised for even greater surface to core uniformity. To insure they'll withstand the tortures of sustained high rpm operation, we subject each batch to the most rigorous real world test standard ever created, SPINTRONTEST II. It's a no holds barred run as high as 9000 RPM where for over 1,000 miles, race ending competitive abuse is continuously revisited. This pass or fail benchmark is the only test of its kind in the performance industry and every set of Tool Room springs conforms to its high standard.Specs:Number of Springs Per Valve:Dual\u003cdiv\u003eOutside Diameter of Outer Spring (in):1.625 in. \u003c\/div\u003e\u003cdiv\u003eCoil Bind Height (in):1.240 in. \u003c\/div\u003e\u003cdiv\u003eDamper Spring Included:Yes \u003c\/div\u003e\u003cdiv\u003eSpring Rate (lbs\/in):545 lbs.\/in. \u003c\/div\u003e\u003cdiv\u003eInside Diameter of Outer Spring (in):1.175 in. \u003c\/div\u003e\u003cdiv\u003eInside Diameter of Inner Spring (in):0.770 in. \u003c\/div\u003e\u003cdiv\u003eValve Spring Style:Standard \u003c\/div\u003e\u003cdiv\u003eCoated:No \u003c\/div\u003e\u003cdiv\u003eQuantity:Sold as a set of 16.\u003c\/div\u003e\u003cdiv\u003eInstalled Height (in):2.120 in. \u003cdiv\u003eSeat Pressure at Installed Height (lbs):265 lbs. \u003c\/div\u003e\n\u003cdiv\u003eOpen Height (in):1.320 in. \u003c\/div\u003e\n\u003cdiv\u003eOpen Pressure (lbs):700 lbs.\u003c\/div\u003e\n\u003c\/div\u003eItems are shipped within one to two business days after full payment has been recieved. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Isky Racing Cams","offers":[{"title":"Default Title","offer_id":44540943630647,"sku":"ISK9955RAD","price":1198.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/91876.jpg?v=1780592322","url":"https:\/\/enginemaster.com.au\/products\/isky-isk9955rad-tool-room-rad9000-valve-springs-1-625-od-265lb-seat-700lb-open","provider":"Engine Master","version":"1.0","type":"link"}
