COMP Cams Spring Seats1.450in X 1.000in X

COMP Cams is well-known for making parts that help engines perform at their best, especially in demanding situations. These valve spring seats are a perfect example of that focus. If you're building a performance engine that will see high RPMs and serious spring pressure, standard shims just won't cut it. These seats are designed to handle that kind of stress and keep your valve springs properly located.

What makes these seats different is their construction and design. They're made from hardened steel, which means they're built to last under extreme conditions. Instead of relying on an outer locating shoulder that requires machining the cylinder head, these use an inboard locating shoulder. This centers the seat and securely holds the spring in place, simplifying installation in many cases. The 1.450-inch outer diameter works well with COMP Cams' 7256 conical valve springs in applications using a .570-inch outer diameter guide.
