What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel. This material is chosen for its strength and durability within the engine.

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

A swedged end is a manufacturing technique where the end of the tube is compressed or flared to create a stronger, more integrated connection point. This helps ensure a solid fit in the valve train.

Are these push rods sold individually or as a set?

This part number, 25104-8, is for a set of eight push rods. This is typically enough for a standard V8 engine configuration.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these push rods are a great example of that. They're built for engines where precise valve train geometry is key. Each push rod measures 7/16 inches in diameter with a 0.165-inch wall thickness and a length of 10.150 inches, designed to work within specific engine builds.

These push rods are constructed from 4130 chrome moly steel, a material chosen for its good strength-to-weight ratio. The ends are meticulously formed with exact radii, and the manufacturing process ensures excellent concentricity and closely controlled lengths, which is important for consistent valve lift and timing. They are heat-treated and finished with a black oxide coating for added durability and corrosion resistance. The swedged end design helps ensure a solid connection point.
