COMP Cams 7903-1 - Checking Push Rod

Magnum Checking Pushrods
These tools make 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 valve train. They are made from a thin wall 5/16” pushrod that is cut and threaded with over 1” travel and feature a 5/16” ball on each end.
