What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel, a well-known material for its strength and durability in performance engine components. They are also heat-treated and finished with a black oxide coating.

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

A swedged end means the end of the push rod has been mechanically formed and thickened, creating a stronger connection point. This is particularly important for the ends that contact the lifter and rocker arm, helping to prevent deformation under stress.

Are these push rods suitable for all engine builds?

These push rods are a well-built component made from strong materials, suitable for many engine builds. It's always best to consult with your engine builder or refer to your specific engine's requirements to ensure compatibility with your build's specifications.
