Why do pushrods have to be stronger than lifters?
On the other hand, increasing the rocker ratio also increases the effort required to open the valves because of the leverage effect. The higher the rocker arm ratio, the greater the force the camshaft, lifters and pushrods have to exert to push the valves open, and the stronger the pushrods have to be to keep from bending.
How do you replace a hydraulic lifter on a rocker?

The pushrods and lifters work with the camshaft and rocker arms to open the engine’s valves. This basic setup has changed little since the earliest days of pushrod engines. The only major change in these components has been roller lifters replacing flat bottom lifters on late model engines.
What’s the thickness of a push rod lifter?
Pushrod wall thicknesses of .080″ to as much as .188″ are also available today for performance engines that demand increased stiffness. For some Top Fuel drag racing applications, solid pushrods are even available (the rocker arms are lubricated by other means).
