Wiseco RED Series Chevy Small Block 350 4.040in Bore 1.125in CH -9.00 CC Piston Set

If you're building a high-performance Chevy Small Block 350 for the track, the Wiseco RED Series pistons are a solid choice. These aren't your average replacement pistons; they're forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of racing and boosted applications.

Wiseco's Race Engineered Design (RED) process means these pistons are specifically shaped for optimal strength-to-weight. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and connecting rod small end properly lubricated under high stress. Plus, the ArmorGlide skirt coating helps cut down on friction and noise, while also reducing wear on the piston skirts and cylinder walls. This set comes complete with premium rings, so you won't have to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

Because these are performance-oriented parts, they are not CARB approved and cannot be shipped to California. This set is designed for a 4.040-inch bore with a 1.125-inch compression height and includes everything needed for a set of eight cylinders.
