What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel, a strong and reliable material chosen for its durability in engine applications. They are also heat treated and finished with a black oxide coating.

Why is push rod length important?

Push rod length is critical for establishing correct valve train geometry. An incorrect length can lead to improper lifter preload, affecting valve sealing and overall engine performance. Always confirm the required length for your specific camshaft and cylinder head combination.

What does 'swedged end' mean?

A swedged end on a push rod means that the end has been mechanically deformed to create a stronger, more integrated connection point. This process helps to prevent separation and ensures the integrity of the push rod under load.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the push rods right is crucial for proper valve train geometry and performance. These push rods from Manley Performance are built for engines where precise valve train operation is key. They are designed to ensure that the lifters are actuated correctly by the camshaft, which directly impacts how efficiently your engine breathes and makes power.

Manley uses 4130 Chrome Moly steel for these push rods, a strong and reliable material that can handle the stresses of engine operation. The ends are meticulously formed with exact radii, and the overall concentricity is closely controlled. This attention to detail means they fit precisely into your valve train setup, helping to maintain consistent geometry. They also feature a swedged end and a black oxide finish for added durability and corrosion resistance.

This set includes eight push rods, enough for a typical V8 engine. Proper push rod length is critical for setting up your valve train correctly, so ensure you've confirmed this 8.350-inch length is appropriate for your specific application and camshaft setup.
