Wiseco RED Series Chevy Big Block 4.155in Bore 1.395in CH 38.00 CC Piston Set

If you're building a performance Chevy Big Block engine, Wiseco's RED Series forged pistons are a solid choice. These pistons are specifically designed for the demands of racing and high-power applications, offering the strength and durability needed to handle serious performance. They are forged and machined in the USA from 2618 aluminum, a material known for its tensile strength, making them well-suited for the stresses of drag racing, circle track, and other demanding uses.

Wiseco has incorporated several thoughtful features into these pistons. The horizontal slot oiling in the pin bores helps ensure the wrist pin and small-end of the connecting rod stay well-lubricated, which is crucial for long service life under high loads. Dedicated forgings allow for an optimized, engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an accumulator groove, which helps maintain consistent ring seal and power delivery. Plus, each set comes complete with premium rings, so you don't have to source them separately.

The ArmorGlide skirt coating on these pistons is another notable feature. It works to reduce operating friction and noise, contributing to a smoother running engine. This coating also helps reduce wear on the piston skirt and cylinder walls, further enhancing durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications and are a key component for anyone looking to build a powerful Chevy Big Block.
