What material is this pushrod made from?

This pushrod is constructed from 4130 chrome moly tubing, a popular choice for its strength and durability in engine components. It also features a heat-treated and black oxide finish.

What does 'swedged end' mean for this pushrod?

A swedged end refers to a process where the end of the tube is compressed or flared to create a specific shape. For this pushrod, it likely refers to the end that fits into the rocker arm or lifter, designed for secure retention.

What is the purpose of the black oxide finish?

The black oxide finish is applied to the heat-treated pushrod to improve its resistance to wear and corrosion. It helps the part stand up better to the constant motion and friction within the engine's valve train.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components. This pushrod is a good example of their attention to detail for your engine build. It's made from 4130 chrome moly tubing, which is a solid choice for durability. The 0.080-inch wall thickness adds to its strength without making it overly heavy.

You'll notice the ends are meticulously formed with exact radii, and the concentricity is excellent. This means the pushrod spins true and the length is closely controlled, which is important for proper valve train geometry. They're also heat-treated and finished with a black oxide coating to help with wear resistance. The swedged end is a common feature that helps with pushrod cup retention.
