  • Manley Nextek

    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.

    • Shotpeened to MIL Specs for maximum fatigue life
    • Proprietary multistep heat treating minimizes load loss
    • Tightly controlled open end flatness reduces valve stem side loading
    • Tip thickness designed to eliminate overload breakage
