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

A pushrod connects the camshaft lifter to the rocker arm. As the camshaft lobe lifts the lifter, the pushrod transfers that motion upwards to the rocker arm, which then opens the engine's intake or exhaust valve.

Why is precise length and concentricity important for pushrods?

Precise length ensures correct valve train geometry, which is crucial for proper valve operation and sealing. Excellent concentricity means the pushrod is perfectly centered, reducing wear on the lifter and rocker arm contact points.

What does the black oxide finish do for these pushrods?

The black oxide finish provides a layer of corrosion resistance, helping to protect the chrome moly steel from rust and wear. It also contributes to the overall durability of the pushrod.

About this part

Product Details

If you're rebuilding your engine's top end, getting the valve train geometry just right is critical for performance and reliability. These pushrods from Manley Performance are a key component in that system, transferring the lift from your camshaft to your rocker arms. They are designed to be a direct replacement for many applications where precise length and strength are needed.

Manley has paid close attention to the details with these pushrods. The ends are meticulously formed with exact radii, which helps ensure proper contact with the lifters and rocker arms. They also feature excellent concentricity and closely controlled lengths, meaning each pushrod in the set is virtually identical, which is important for consistent valve train operation. The chrome moly construction offers good strength for the demands of engine operation, and the heat treatment and black oxide finish add durability and corrosion resistance.
