{"product_id":"manley-valve-spring-spring-1-500-double-4","title":"Manley Valve Spring SPRING-1.500 DOUBLE","description":"From drag strips to short track and endurance circuits, the Manley NexTek® series is engineered for serious racers. 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.\r\n\u003cul\u003e\t\u003cli\u003eHigher natural frequency and lower active mass provides improved valvetrain control and higher RPM potential\u003c\/li\u003e\r\n\t\u003cli\u003eDual spring design reduces friction, which generates less heat and translates into greatly reduced load loss\u003c\/li\u003e\r\n\t\u003cli\u003eExtensively tested on the Spintron, dyno and race track (including blown nitro engines) and proven highly effective\u003c\/li\u003e\r\n\t\u003cli\u003eSmaller diameter, lightweight dual design allows engine to rev higher with improved valve train control\u003c\/li\u003e\r\n\t\u003cli\u003eAccepts smaller, lighter retainers which also promotes higher revs\u003c\/li\u003e\r\n\t\u003cli\u003eUltra clean, high tensile strength chrome silicon material\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eAttributes:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eManley\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00807298039541\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eAverage Gram Weight: \u003c\/b\u003e139\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eEngine Type: \u003c\/b\u003eICE\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIndustry: \u003c\/b\u003eAutomotive\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eInstalled Pressure and Height: \u003c\/b\u003e330 @ 2.100\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eOpen Pressure and Height: \u003c\/b\u003e1050 @ 1.200\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eOut of Stock Message: \u003c\/b\u003eCall for Availability\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eProduct Market: \u003c\/b\u003eDomestic\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eProduct Type: \u003c\/b\u003eEngine Valve Spring\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Lift - Maximum: \u003c\/b\u003e0.900\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Spring Coil Bind Height: \u003c\/b\u003e1.130\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Spring Inner Diameter: \u003c\/b\u003e0.710\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Spring Material: \u003c\/b\u003eChrome Silicon\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Spring Outer Diameter: \u003c\/b\u003e1.500\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Spring Quantity: \u003c\/b\u003e1\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Spring Rate: \u003c\/b\u003e800\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eValve Spring Series: \u003c\/b\u003eNexTek?
