Made from 4130 chromoly steel. Both pushrod tubes and ends are designed to withstand the demands of high RPM and heavy spring loads. 3/8" diameter resists flex to prevent damage to other valve-train components. When buying pushrods be sure it's chromoly, not just steel. OAL (10.650") is the overall length with both tips installed.
