NexTek® springs resist pressure loss and valve-train degradation even in the most demanding race conditions. That means more consistent spring force deep into a run, reduced valve bounce, and improved overall stability for high-RPM performance. Built to outperform and outlast in real-world competition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eExtensively tested on the Spintron, dyno and race track (including blown nitro engines) and proven highly effective\u003c\/li\u003e\n\u003cli\u003eHigher natural frequency and lower active mass provides improved valvetrain control and higher RPM potential\u003c\/li\u003e\n\u003cli\u003eDual spring design reduces friction, which generates less heat and translates into greatly reduced load loss\u003c\/li\u003e\n\u003cli\u003eSmaller diameter, lightweight dual design allows engine to rev higher with improved valve train control\u003c\/li\u003e\n\u003cli\u003eAccepts smaller, lighter retainers which also promotes higher revs\u003c\/li\u003e\n\u003cli\u003eUltra clean, high tensile strength chrome silicon material\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Manley Performance","offers":[{"title":"Default Title","offer_id":45291739513151,"sku":"MAN221461-16","price":999.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/2041\/6831\/products\/d5d40c7892594cb55df535f7f5e4a6f4_10e8cb03-4bb0-4560-8cb1-1e53df1813c4.jpg?v=1686086352","url":"https:\/\/smgspeed.com\/products\/manley-alcohol-fuel-classes-promod-nextek-series-high-performance-valve-springs","provider":"SMGspeed","version":"1.0","type":"link"}
