Wiseco Chevrolet Small Block -5.7cc Flat Top 1.125 X 4.020 - Set of 8

If you're rebuilding a high-performance Chevrolet small block engine, especially for racing or adding significant power, you need pistons that can handle the stress. Wiseco's RED Series forged pistons are built for exactly that kind of demanding environment. They use a Race Engineered Design to give you the strength and durability required for serious performance, along with precision features that help you gain a competitive edge.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard, particularly with forced induction or other power adders. Wiseco has incorporated horizontal slot oiling in the pin bores to ensure the wrist pin and small end of the connecting rod stay well-lubricated, which is key for long service life under stress. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a low weight to keep things efficient.

You'll also find an accumulator groove designed to help maintain consistent ring seal and power delivery. Plus, each set comes with premium rings, so you don't have to hunt for compatible ones separately. The ArmorGlide skirt coating is a notable feature that works to reduce friction and noise during operation, while also minimizing wear on the piston skirt and cylinder wall. These are a solid option for anyone serious about building a powerful Chevrolet small block.
