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

Pushrods connect the lifters to the rocker arms in an overhead valve engine. They transfer the up-and-down motion from the camshaft's lobe, through the lifter, to the rocker arm, which then opens the engine's valves.

Why is the length and diameter of a pushrod important?

Correct pushrod length is critical for proper valve train geometry and geometry. Incorrect length can lead to poor valve sealing, reduced performance, and premature wear on components like lifters and rocker arms. Diameter affects stiffness.

What does 'swedged end' mean for these pushrods?

A swedged end means the tube has been compressed and expanded at the end to create a stronger, thicker wall section. This provides a more robust connection point for the rocker arm and lifter, improving durability.

Product Details

If you're rebuilding the top end of your engine, getting the valve train geometry just right is crucial for performance and longevity. These pushrods from Manley are a key component in ensuring your valvetrain operates as intended. They transfer the motion from your lifters to your rocker arms, and their precise dimensions are critical for proper valve lift and timing.

Manley builds these pushrods from 4130 chrome moly tubing, which offers a good balance of strength and weight for performance applications. The ends are meticulously formed with exact radii, and the overall concentricity is closely controlled. This attention to detail means they fit right and work consistently. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance. The swedged ends provide a strong connection point for the rocker arms and lifters.

This set includes 16 pushrods, enough for a typical V8 engine. Ensuring you have the correct length and wall thickness is important for your specific engine build, so double-check your measurements before ordering.
