Stage V

Stage V by Manton

Founded in 1984 by Eric Hansen and Bill Stel, Stage V Engineering revolutionized Chrysler Hemi performance by developing innovative, heavy-duty rocker arms and cylinder heads designed to solve critical valvetrain challenges in extreme racing environments like Top Fuel. Originally created to enable Hemi-style cylinder heads to fit on standard wedge blocks through custom geometry, the company pioneered low-friction roller tips and fully serviceable, rebuildable components that served generations of street and racing applications. Today, Manton Racing Products proudly manufactures, services, and preserves this legendary product line, ensuring that Stage V's systems-based valvetrain engineering continues to support modern high-performance Hemi engine builders.
