What is the primary function of a pushrod in an engine?

A pushrod connects the rocker arm to the lifter in an overhead valve engine. It transfers the motion from the camshaft lobe, via the lifter, to the rocker arm, which then opens the valve.

Why is precise length and concentricity important for pushrods?

Precise length ensures correct valvetrain geometry, which affects valve lift and duration. Excellent concentricity means the pushrod is perfectly centered, reducing wear on the lifter and rocker arm contact points and ensuring smooth operation.

What does the black oxide finish do for these pushrods?

The black oxide finish provides a layer of corrosion resistance to the steel pushrod. It also helps to reduce friction where the pushrod contacts the lifter and rocker arm.
