Wiseco RED Series Chevy Small Block 350 4.000in Bore 1.125in CH -9.00 CC Piston Set

If you're building a high-performance Chevy Small Block 350, this Wiseco RED Series piston set is a solid choice. These pistons are specifically made for a 4.000-inch bore and are designed to handle the demands of racing and boosted applications. Wiseco's Race Engineered Design (RED) process means these aren't just generic pistons; they're built with precision features to give you an edge on the track or street.

Crafted in the USA from 2618 aluminum, these pistons offer the tensile strength needed for serious performance. They feature horizontal slot oiling in the pin bores to keep the wrist pins and small end of the connecting rods well-lubricated, which is crucial for longevity. The dedicated forgings allow for an optimized, engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. Each set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove helps maintain consistent ring seal for optimal power delivery.

This set includes eight pistons, rings, and wrist pins, ready for your engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended clearances.
