  • Up for sale is a rare, original Genuine Harley-Davidson Valve Spring Set (Part #18203-83). This is an authentic New Old Stock (NOS) engine rebuild component kit containing a full engine matching set of four (4) springs.
    The springs are perfectly preserved inside the original factory-sealed Harley-Davidson "Genuine Parts & Accessories" plastic packaging. The label prominently features the highly legible factory inspection stamp "1083", dating this exact pack to October 1983. This makes it an exact production match for early-run 1984 model year motorcycles.
    These heavy-duty coiled steel outer springs are critical components for any museum-grade Ironhead overhaul, cylinder head restoration, or valve train refresh where period-correct authenticity matters.
