Wiseco RED Series Chevy Small Block 350 4.005in Bore 1.125in CH -9.00 CC Piston Set

If you're rebuilding the heart of your Chevy Small Block 350 for serious performance, especially for drag racing or circle track, you need pistons that can handle the stress. Wiseco's RED Series pistons are built with Race Engineered Design (RED) principles to give you the strength and precision required for demanding engine builds. These aren't your average replacement parts; they're crafted for competition.

Forged from 2618 aluminum right here in the USA, these pistons offer the tensile strength needed for high-horsepower applications and power adders. Wiseco incorporates several thoughtful features to ensure longevity and performance. Horizontal slot oiling in the pin bores keeps the wrist pin and connecting rod small end properly lubricated, which is crucial for preventing wear. The dedicated forgings allow for an optimized, engine-specific strutted design, maximizing strength while keeping weight down. Plus, each set comes complete with premium rings, so you won't have to hunt for compatible ones.

To further reduce friction and wear, these pistons feature an ArmorGlide skirt coating, which also helps quiet down operation. An accumulator groove is included to help maintain consistent ring seal and power delivery under extreme conditions. This set is designed for a 4.005-inch bore with a 1.125-inch compression height and a -9.00cc dish, making them a solid choice for many performance Small Block 350 builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
