What material are these pushrods made from?

These pushrods are constructed from 4130 chrome moly steel. This material is known for its strength and durability, making it suitable for performance engine builds.

What does 'swedged end' mean?

A swedged end means the tube has been compressed and thickened at the end, creating a stronger connection point. This is often done to reinforce the ends where they contact the lifter and rocker arm.

Are these pushrods balanced?

While not explicitly stated as 'balanced,' these pushrods feature excellent concentricity and closely controlled length. This ensures consistency within the set, which is crucial for proper valve train operation.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for performance applications, getting the pushrods right is key. These pushrods from Manley Performance are made from 4130 chrome moly steel, a strong material that can handle the stresses of higher lift cams and increased spring pressures without flexing.

Manley paid close attention to the details here. The ends are meticulously formed with exact radii, which helps ensure they seat properly against the rocker arms and lifters. They also have excellent concentricity and closely controlled length, meaning each pushrod in the set is very similar to the others. This consistency is important for proper valve train geometry. They're heat treated and finished with a black oxide coating to help prevent corrosion.
