They feature a proprietary, multi-step heat-treating that minimizes load loss and have computer-aided modeling to minimize valve bounce and valve gear separation. The Manley NexTek valve springs are smaller diameter and lightweight, allowing engines to rev higher faster. They have an extended tip thickness designed to eliminate overload breakage, and their tightly controlled open-end flatness reduces valve stem side loading.\u003c\/p\u003e \u003cbr\u003e\u003cbr\u003e\u003cul\u003e  \u003cli\u003eNumber of Springs Per Valve: Dual\u003c\/li\u003e  \u003cli\u003eOutside Diameter of Outer Spring (in): 1.295 in.\u003c\/li\u003e  \u003cli\u003eCoil Bind Height (in): 1.100 in.\u003c\/li\u003e  \u003cli\u003eDamper Spring Included: No\u003c\/li\u003e  \u003cli\u003eSpring Rate (lbs\/in): 379 lbs.\/in.\u003c\/li\u003e  \u003cli\u003eInside Diameter of Inner Spring (in): 0.676 in.\u003c\/li\u003e  \u003cli\u003eValve Spring Style: Standard\u003c\/li\u003e  \u003cli\u003eValve Springs Coated: No\u003c\/li\u003e  \u003cli\u003eQuantity: Sold individually.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Manley","offers":[{"title":"Default Title","offer_id":44680656716087,"sku":"MAN221436-1","price":65.85,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/101388.jpg?v=1780426419","url":"https:\/\/enginemaster.com.au\/products\/manley-man221436-1","provider":"Engine Master","version":"1.0","type":"link"}
