What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a material chosen for its strength and durability in high-performance engine applications. They are also heat treated and finished with a black oxide coating.

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

A swedged end refers to a type of end construction where the material is compressed or formed to create a stronger, often tapered, connection point. This design is common in push rods to ensure a solid and reliable interface within the valve train.

Are any installation tools or hardware included with this set?

This product listing is for the set of 16 push rods only. Installation typically requires specific tools for valve train assembly, and any necessary hardware like valve locks or retainers would need to be sourced separately.
