What is the purpose of pushrods in an engine?

Pushrods are part of the valvetrain system. They transfer the motion from the camshaft to the rocker arms, which then open the intake and exhaust valves. Proper length and rigidity are crucial for correct valve timing and operation.

What does 'swedged end' mean for these pushrods?

Swedged ends refer to the way the ends of the pushrod are formed. This process creates a strong, integrated end with precise radii, which helps ensure a good fit against the lifter and rocker arm, reducing potential wear points.

What is the benefit of heat-treated and black oxide finished pushrods?

Heat treating strengthens the pushrod material, making it more resistant to bending or flexing under the stress of engine operation. The black oxide finish adds a layer of corrosion resistance and can also help with lubrication retention.

About this part

Product Details

Manley Performance is a well-known name in the performance engine world, and they've put that expertise into these pushrods. If you're rebuilding or modifying your engine's valvetrain, these pushrods are designed to handle the job. They measure 7.300 inches long, have a .080 inch wall thickness, and a 5/16 inch diameter, with a set of eight included.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, which helps ensure they seat properly and reduce wear. They also boast excellent concentricity, meaning the wall thickness is very consistent around the entire pushrod. This is important for maintaining stable valvetrain geometry under load. They've been heat treated and finished with a black oxide coating for durability.
