COMP Cams Magnum Pushrod Checking Kit makes it easy and economical to lay out and determine proper pushrod length during a high performance engine rebuild. This is necessary for correct valve train geometry to obtain the desired results from the cam and to ensure damage is not done to the rest of the valvetrain. They are made from a thin wall 5/16" pushrod that is cut and threaded with over 1" of travel and features a 5/16" ball on each end.
