Wiseco RED Series Chevy Small Block 350 4.000in Bore 1.550in CH -11.00 CC Piston Set

Starting with a 4.000 inch bore size and a 1.550 inch compression height, this set of eight Wiseco RED Series pistons is built for serious performance in Chevy Small Block 350 engines. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing the limits with racing or adding significant power. The RED series, which stands for Race Engineered Design, means Wiseco has put a lot of thought into optimizing these parts for competitive use.

Wiseco machines these pistons in the USA, and they've included some smart features to help them last and perform. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and the small end of the connecting rod well-lubricated, a critical factor for durability under high stress. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also helping to cut down on wear on both the piston skirt and the cylinder wall. Each set comes complete with premium rings, so you won't have to hunt for those separately, and an accumulator groove helps ensure the rings maintain a consistent seal for steady power delivery.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevy Small Block 350 and need pistons that can handle the demands of racing, drag strip, or circle track, this set from Wiseco is a well-built option designed for that purpose.
