What material are these push rods made from?

These Manley Performance push rods are constructed from 4130 chrome moly tubing. This material is chosen for its strength and durability in engine applications.

What does 'swedged end' mean for these push rods?

A swedged end means the tubing has been compressed and formed at the end, creating a stronger, more rigid connection point. This design helps prevent flexing under load.

Are these push rods suitable for all engine builds?

These push rods are designed for engine builds where precise valve train geometry and consistent length are important. It's always best to consult your engine builder or Manley Performance's specifications to ensure they are the correct choice for your specific application.

About this part

Product Details

These are Manley Performance push rods, part number 25140-8. They measure 7/16 inches in diameter with an 8.200-inch length and a 0.165-inch wall thickness. This set includes eight push rods, made from 4130 chrome moly tubing. They are designed for engine builds where precise valve train geometry is critical.

Manley forms the ends of these push rods with exact radii and pays close attention to concentricity, ensuring they are straight and true. The length is also closely controlled, which is important for consistent valve lash settings. They are heat-treated for added strength and finished with a black oxide coating to help prevent corrosion. The swedged end design adds further rigidity where it's needed most.

When rebuilding or modifying an engine, the push rods are a key component in transferring the camshaft's motion to the valvetrain. Using well-made push rods like these from Manley helps ensure reliable operation and consistent performance from your engine.
