The self damping characteristic of conical geometry, along with the lower spring kinetic energy of the upper coils, provide a game-changing breakthrough in valve spring design. COMP Cams Dual Conical Valve Springs are constrained at the top and bottom with stepped retainers and spring seats to create separation. The result is that the springs naturally progressive nature can provide outstanding damping without rubbing friction or the associated heat and+D6566 surface damage. These springs are designed for circle track, road Race and drag racing Applications, as well as all-out, high-RPM street\/strip hydraulic Roller valve train systems with optimized lifters.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eSeat Height: 2.05 IN\n\u003c\/li\u003e\u003cli\u003eSeat Pressure: 150 PS\n\u003c\/li\u003e\u003cli\u003eCompatible .570\" Guide Diameter Spring Seats: 4669-16\n\u003c\/li\u003e\u003cli\u003eCoil Bind Height: 1.115 IN\n\u003c\/li\u003e\u003cli\u003eValve Spring Series: Race Endurance\n\u003c\/li\u003e\u003cli\u003eSpring Rate: 600\n\u003c\/li\u003e\u003cli\u003eOuter Top Spring Outside Diameter: 1.442 IN\n\u003c\/li\u003e\u003cli\u003eCompatible Shims: 4756\n\u003c\/li\u003e\u003cli\u003eOuter Top Spring Inside Diameter: 1.01 IN\n\u003c\/li\u003e\u003cli\u003eOuter Bottom Spring Outside Diameter: 1.657 IN\n\u003c\/li\u003e\u003cli\u003eOuter Bottom Spring Inside Diameter: 1.225 IN\n\u003c\/li\u003e\u003cli\u003eNumber of Springs: 2\n\u003c\/li\u003e\u003cli\u003eInner Spring Inside Diameter: 0.646\/0.861 IN\n\u003c\/li\u003e\u003cli\u003eDamper: No\n\u003c\/li\u003e\u003cli\u003eCompatible Retainer: 716-16\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eEngine Valve Spring Kit\u003c\/li\u003e","brand":"Comp Cams","offers":[{"title":"Default Title","offer_id":52886153560427,"sku":"CCA-7245-16","price":639.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/CCA-7245-16-1.jpg?v=1770607878","url":"https:\/\/caautoparts.com\/products\/engine-valve-springs-cca7245-16","provider":"CA Auto Parts","version":"1.0","type":"link"}
