What material are these pushrods made from?

These pushrods are constructed from 4130 Chrome Moly tubing, a material known for its strength and durability in high-stress applications like engine components.

Why is the length and concentricity of pushrods important?

Precise length and excellent concentricity are crucial for proper valve train geometry. This ensures that your lifters and rocker arms operate correctly, which is vital for consistent engine performance and reliability.

What is the purpose of the black oxide finish?

The black oxide finish, along with heat treatment, helps to protect the pushrods from corrosion and wear. This contributes to their longevity within the engine.
