Edelbrock hardened guide plate kit part #9662 is made from high‑grade alloy steel hardened to 60 Rockwell C and supplied in sets of eight. Stepped plates support pushrods closer to the rocker arms to stabilize them, reducing side loading and improving valvetrain geometry in 5.2L/5.9L Magnum engine applications. The hardened finish and stepped design deliver durable support where pushrod alignment and stability are important for reliable valvetrain function.
