Collection: Valve Train for Harley-Davidson, Indian & Metric Motorcycles

Every intake, compression, power stroke, and exhaust stroke depends on a single, precisely coordinated mechanical ballet – the valvetrain. The valvetrain encompasses all the components that translate the camshaft's motion into the precise, timed opening and closing of the valves: lifters, pushrods, rocker arms, valves, valve guides, and valve springs. If any of these components wear out, loosen, or are improperly adjusted, the engine will immediately signal it – with knocking sounds, uneven compression, power loss, or even serious engine damage. Our selection includes valvetrain components for Harley-Davidson, Indian, and metric custom motorcycles: hydraulic and mechanical lifters, pushrods, rocker arms, valves, valve guides, valve seats, and valve springs. We offer factory-spec replacement parts, as well as heavy-duty, performance-enhanced solutions designed for higher RPMs and more aggressive cam profiles. Quality parts are manufactured with precision from high-strength materials to perform their job accurately, quietly, and reliably, whether for daily use or a serious performance-enhancing project. Whether the valvetrain overhaul is part of replacing a worn component, a complete engine rebuild, or a cam change, you will find the parts that fit your motorcycle precisely with us.
