Manley Performance introduced the NexTek® (Next Technology) line of valve springs developed to satisfy the needs of top level engine builders demanding the absolute highest quality valve springs. What started out as only a very small handful of part numbers, specifically designed for the roller cam “BGN” market and high-end Drag Racing arena (Pro Stock/Comp), has evolved into an expansive array of successful part numbers for a wide variety of drag, oval, marine and street/strip applications. Manley Nextek® springs can be found in drag race applications ranging from Bracket to Top Fuel, in oval track engines across the country such as DLM and Sprint cars, as well as in late model Chevy LS, Chrysler 5.7L/6.1L Hemi and Ford Modular vehicles on the street and strip
