What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a material known for its strength and relatively light weight, making it suitable for performance engine builds.

What does 'swedged end' mean for a push rod?

A swedged end is formed by compressing the material to create a stronger, more durable connection point. This design, combined with meticulously formed radii, ensures a precise fit and reliable operation within the valve train.

What is the benefit of excellent concentricity and controlled length?

Excellent concentricity means the push rod is perfectly straight and the wall thickness is uniform. Closely controlled length ensures consistency across all push rods, which is vital for accurate valve timing and preventing potential interference issues in the engine.

Product Details

Manley Performance has a solid reputation for making well-built engine components, and these push rods are no exception. If you're rebuilding your top end or just need to replace worn-out push rods, this set is a strong option. They're made from 4130 chrome moly steel, which offers a good balance of strength and weight for performance applications.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and they maintain excellent concentricity. This means the push rod is perfectly straight and the wall thickness is closely controlled, which is crucial for consistent valve train operation. They're also heat treated and finished with a black oxide coating to help with durability and corrosion resistance.
