Product Details
This set includes four dual valve springs from Ferrea, designed for 1984-1998 Harley-Davidson Evolution engines. These springs are built to handle the demands of performance engine builds, offering improved valve control and stability at higher RPMs.
Each spring features a dual-wound design, providing a strong seat pressure and open pressure combination that helps prevent valve float. The specific dimensions, with an outer diameter of 1.005 inches and an inner diameter of 0.730 inches at the seat, and 1.530 inches OD and 1.110 inches ID at full lift, are engineered to work with specific camshaft profiles and valve train setups common in these Harley-Davidson engines. Ferrea is known for well-built components, and these springs are a solid option for anyone rebuilding or upgrading their Evolution engine's top end.
