Wiseco Chevy SB RED Series Piston Set 4130in Bore 1425in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine for racing or serious street use, Wiseco's RED Series pistons are a solid choice. These aren't your average pistons; they're forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demanding conditions of performance racing and applications with power adders like turbochargers or superchargers. The Race Engineered Design (RED) philosophy behind these pistons means they're built with precision-machined features to give you a competitive edge.

Wiseco machines these pistons in the USA, and they've incorporated several thoughtful details. The horizontal slot oiling in the wrist pin bores helps ensure the wrist pin and the small end of the connecting rod stay well-lubricated, which is crucial for long service life in a high-stress engine. Dedicated forgings allow for an optimized, engine-specific strutted design, meaning Wiseco engineers the shape to maximize strength while keeping the weight down. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also helping to minimize wear on both the piston skirt and the cylinder wall. Each set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

This set is designed for a 4.130-inch bore, has a 1.425-inch compression height, and uses a 0.927-inch wrist pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, these Wiseco RED Series pistons offer a well-built foundation.
