What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, which is known for its strength and durability in 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 means the tube has been compressed and shaped at the end. This design helps create a strong, reliable connection point within the valve train assembly.

Why is concentricity important for push rods?

Excellent concentricity means the push rods are very round and consistent. This precise manufacturing ensures proper valve train geometry, which is vital for smooth engine operation and overall performance.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the push rods right is crucial for proper valve train geometry. These push rods from Manley Performance are made from 4130 chrome moly, a strong and reliable material for this application. They feature a swedged end, which is a common design that helps ensure a solid connection within the valve train.

Manley has paid close attention to the details here. The ends are meticulously formed with exact radii, and the concentricity is excellent, meaning they are very round and consistent. This close control over length and form is important for maintaining the correct geometry in your engine's valve train, which directly impacts performance and reliability. They also come with a heat-treated and black oxide finish, adding a layer of durability and corrosion resistance.

This set includes eight push rods, which is what most V8 engines require. Having a well-built set like these can make a notable difference in how smoothly your engine runs after a rebuild.
