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.","brand":"Manley Performance","offers":[{"title":"Default Title","offer_id":44491859525839,"sku":"MAN221443-16","price":529.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/4164\/7055\/files\/Manley-NexTek-Series-1580-OD-832-ID-730-Lift-Oval--1758668469.webp?v=1758668470","url":"https:\/\/www.cimotorsports.com\/products\/manley-nextek-series-1-580-od-832-id-730-lift-oval-track-and-endurance-valve-springs","provider":"CI Motorsports","version":"1.0","type":"link"}
