What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly tubing. This material is known for its strength and durability, making it a popular choice for performance engine components.

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

A swedged end means the tubing has been compressed and formed at the end, creating a stronger, more rigid connection point. This helps prevent flexing and ensures consistent contact with the rocker arm and lifter.

Are these push rods adjustable?

No, these are fixed-length push rods. Proper length is critical for valve train geometry, and it's important to verify the correct length for your specific engine build before installation.
