Wiseco RED Series Chevy Small Block 400 4.165in Bore 1.425in CH -21.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This RED Series piston set is built for the Chevrolet Small Block 400 engine, designed to handle the demands of racing and serious performance builds. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard, especially with power adders like turbos or superchargers.

The Race Engineered Design, or RED, means these pistons have features specifically machined to give you an edge. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and small-end of the connecting rod well-lubricated, helping them last longer under stress. Wiseco uses dedicated forgings for each engine application, allowing them to create an optimized, strutted design that maximizes strength while keeping the weight down. Each set also comes with premium rings, so you don't have to hunt for compatible ones. Plus, the ArmorGlide skirt coating not only helps reduce friction and noise but also cuts down on wear to the piston skirt and cylinder wall. An accumulator groove is included to help maintain consistent ring seal and power output.

This set is for an 8-cylinder engine and features a 4.165-inch bore with a 1.425-inch compression height. Please note that these pistons are not CARB approved and cannot be shipped to California. For installation, it's always best to refer to the manufacturer's detailed instructions to ensure proper fitment and performance.
