The COMP Cams ID spring seat 4714 is a hardened steel inboard locator that centers and holds the valve spring while protecting the head and shim under extreme spring pressures and high RPM. With a 1.600" outer diameter and a .570" inner diameter, the 4714 is specified to work well with COMP 951 dual valve springs, offering a matched hardened seat for that spring family.
