What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly tubing. This material is known for its strength and durability, making it suitable for engine components.

What is the purpose of the swedged ends and black oxide finish?

The swedged ends are meticulously formed with exact radii to ensure excellent concentricity and closely controlled length. The black oxide finish helps protect the push rods and contributes to their durability under engine operating conditions.

Are these push rods suitable for all engine builds?

These push rods are a well-built option for engine builds where precise valvetrain geometry is important. Always confirm that the 3/8 inch diameter, 6.350 inch length, and 0.135 inch wall thickness are appropriate for your specific engine application and camshaft requirements.

About this part

Product Details

These Manley push rods are made from 4130 chrome moly tubing with a 0.135 inch wall thickness and a 3/8 inch diameter, measuring 6.350 inches long. The swedged ends are meticulously formed with exact radii, ensuring excellent concentricity and closely controlled length. This attention to detail is important for proper valve train geometry and consistent engine performance.

The heat treatment and black oxide finish on these push rods help them stand up to the demands of an engine.
