NexTek Valve Springs...Better By Design!

Manley NexTek (Next Generation) Valve Springs were developed over a decade ago and still offer unequaled performance. The NexTek springs were developed to satisfy the demands of top level engine builders who demanded the absolute highest quality valve springs. Manley Nextek springs can be found in drag race applications ranging from Bracket racers to Top Fuel, in oval track engines across the country such as DLM and Sprint cars, late model Chevy LS, Chrysler 5.7L/6.1L Hemi and Ford Modular engines on the street and strip.

Features:
  • Higher natural frequency and lower active mass provides improved valvetrain control and higher RPM potential
  • Dual spring design reduces friction, which generates less heat and translates into greatly reduced load loss
  • Extensively tested on the Spintron, dyno and race track (including blown nitro engines) and proven highly effective
  • Smaller diameter, lightweight dual design allows engine to rev higher with improved valve train control
  • Accepts smaller, lighter retainers which also promotes higher revs
  • Ultra clean, high tensile strength chrome silicon steel
  • Super Finished multi-step surface enhancement significantly improves fatigue strength
  • Ideal loads for multiple applications with minimal load loss
