Cat Pushrod Guideplates

 Cat pushrod guideplates are necessary in high-rpm motors. They keep your pushrods in line with your lifter cups and rocker arms—and prevent deflecting or walking sideways. The guideplates are hardened to prevent premature wear. They're available in sizes and styles for fitment on a variety of engine applications.
