PRW pushrods are ideal for serious street performance and race applications. As an essential component in an engine's valvetrain system, the primary function of a pushrod is to transmit the vertical motion of the camshaft to the rocker arms. As the lobes of the rotating camshaft lift the pushrods, they push against the rocker arms, causing them to pivot and open the valves. The length of a pushrod is critical to ensure proper valvetrain geometry, therefore, it should be carefully selected to maintain the correct relationship between the camshaft, pushrod, rocker arms, and valves. Choose the PRW pushrods designed for your application needs. Key features: * One-piece construction from .080 in. wall, seamless chromoly * Heat-treated for extended durability and guide plate compatibility * Precision formed and reinforced ends * Black-oxide finished with laser etched length
