Semi-finished, multi-piece pushrods allow you to personally craft the exact pushrod needed for your high performance application. Simply choose your desired shaft length, shaft diameter, wall type, wall thickness, ball end diameter and end type. Many components are also available in 200 and 400 piece Engine Builder Kits. When ordering semi-finished pushrods, you must also order the proper pushrod cutter. Because there are so many variables involved, to order you must contact a trained COMP Cams® technician, who will help you order your semi-finished, multi-piece pushrods.
