Wiseco RED Series Chevy Small Block 400 4.165in Bore 1.125in CH -12.00 CC Piston Set

Wiseco is well-known for its forged pistons, and their RED Series takes that expertise and applies it to performance racing applications. If you're building a Chevy Small Block 400 for serious competition, these pistons are designed to handle the demands of the track. They utilize Race Engineered Design (RED) to offer the strength and durability that performance engines need, combined with precision-machined features that give you a competitive edge.

These pistons are forged and machined in the USA from 2618 aluminum, chosen for its high tensile strength, which is crucial for performance racing and applications using power adders. To further enhance their performance and longevity, they feature horizontal slot oiling in the pin bores. This design helps maintain optimal wrist pin and small-end lubrication, which is critical for a long service life under high stress. The dedicated forgings allow for an engine-specific, strutted design that maximizes the strength-to-weight ratio, meaning you get robust construction without unnecessary mass. Each set also comes with premium rings, so you don't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

Additionally, these pistons feature an ArmorGlide skirt coating. This advanced coating is designed to reduce operating friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. This combination of robust materials, smart design features, and protective coatings makes this set a solid choice for anyone looking to build a high-performance Chevy Small Block 400 engine.
