What is the primary function of pushrods in an engine?

Pushrods are part of the valvetrain assembly. They transfer the lifting motion from the lifters, which are actuated by the camshaft, to the rocker arms. This motion ultimately opens the engine's intake and exhaust valves.

Why is the length and diameter of pushrods important?

Correct pushrod length is crucial for setting up the rocker arm geometry. Incorrect length can lead to premature wear on the valvetrain components. The diameter affects rigidity and compatibility with specific lifter and rocker arm designs.

What does 'swedged end' mean for these pushrods?

A swedged end is a forming process where the end of the tube is compressed and shaped. For these pushrods, it means the ends are precisely formed with exact radii, ensuring a solid and concentric connection point with the lifter and rocker arm.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for a performance application, getting the valve train geometry just right is critical. These Manley pushrods are a key piece of that puzzle. They connect the lifters to the rocker arms, transferring the motion that opens and closes your valves. Getting this length and diameter correct ensures your valvetrain operates smoothly and efficiently.

Manley built these pushrods from strong chromoly steel, a popular choice for its durability and ability to handle the stresses of an active engine. They've paid close attention to the ends, forming them with exact radii for excellent concentricity. This means they'll seat properly in the lifters and rocker arms, reducing wear and ensuring consistent operation. The closely controlled length is also vital for setting up your rocker arm geometry correctly, which is especially important when you've changed camshafts or cylinder heads. They come with a heat-treated and black oxide finish for added durability.
