Pushrods can have two different lengths depending on it they are ball and cup or ball and ball. Ball and ball have one length, the overall length, from the tip of one ball to the tip of the ball on the other end scope
Ball and cup have two different lengths, overall and effective length, the overall total length is measured the same as a ball and ball, from the bottom of the ball to the top of the cup wrench The effective length is from the bottom of the cup to the tip of the ball[b]. I use a 5/16 ball set in the cup and measure the overall length from the top of the bearing to the tip of the ball and the other end and then subtract half of the diameter of the ball bearing which is .156 scope
There are many choices on pushrods other than the type and lengths, the diameter of the tube, the thickness of the wall, the design of the wall, straight, single taper or dual taper and if they are heat treated or not.
IHTH.
