NexTek Valve Springs...Better By Design!
Higher natural frequency provides improved valvetrain control and higher RPM potential
All springs are triple design springs except for 660-221424, 660-221425 & 660-221454 which are double design without damper
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
Better valvetrain stability and component life
Ultra clean, high tensile strength chrome silicon steel
Polish Finish surface reduces friction, improves fatigue life and minimize load loss.
Ideal loads for multiple applications with minimal load loss
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 on the street and strip.
