These COMP Cams ID spring locators feature a hardened steel inboard shoulder and a 1.450" outside diameter to center and hold valve springs securely. The 4694-style seats work with compatible conical springs in .570" guide sizes, providing repeatable seating, protecting the head and shim from high spring pressures, and avoiding the extensive machining older cup-style retainers sometimes require.
