What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel, known for its strength and durability. They also feature a heat treatment and black oxide finish for added wear resistance.

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

A swedged end refers to a method of joining or forming the end of the tube, creating a strong, integrated connection. This design contributes to the overall durability and reliability of the push rod.

Why is concentricity important for push rods?

Excellent concentricity means the push rod is perfectly centered along its length. This ensures it spins true and makes consistent contact with the rocker arm and lifter, which is vital for a smooth-operating and efficient valve train.
