Sealed Power Speed Pro 351W Hypereutectic Pistons .030 Over – Flat Top Set Of 8 With Wrist Pins

Ready to breathe some serious life back into that old 351W?

This set of eight Sealed Power / Speed Pro pistons is exactly what your Ford 5.8L has been waiting for.

They're hypereutectic, which is just a fancy way of saying they're super strong and ready to handle some heat without beating up your cylinder walls.

The skirts are coated to cut down on friction, and the tops are flat—perfect for building compression without getting in the way of your heads.

These are brand new, .030 over, and come with the wrist pins included so you've got everything you need to get your rotating assembly moving.

Just a heads up, they're made in India but meet all the quality you'd expect from the Speed Pro name.

And yeah, because it's California, there's a Prop 65 warning—pretty much everything fun has one these days.

Whether you're building a cruiser or a weekend warrior, these slugs are a solid pick.
