Wiseco RED Series Chevy Small Block 400 4.185in Bore 1.550in CH -15.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance Chevy Small Block 400 engines. The RED (Race Engineered Design) series is all about combining the strength needed for racing applications with precision features that give you an edge. Whether you're building for drag racing, circle track, or any high-performance street application, these pistons are a solid foundation.

Wiseco machines these pistons in the USA, and they've included some smart details to ensure longevity and consistent performance. The horizontal slot oiling in the pin bores is a key feature, keeping the wrist pin and connecting rod small end well-lubricated, which is crucial for preventing wear under high stress. They also use dedicated forgings, meaning the shape of each piston is optimized for the specific engine, maximizing strength while keeping weight down. Plus, the ArmorGlide skirt coating isn't just for show; it helps reduce friction and noise, and it cuts down on wear to the piston skirt and cylinder wall. You also get premium rings included with each set, so you don't have to hunt for compatible ones.

This set is designed for a 4.185-inch bore with a 1.550-inch compression height and a -15.00cc dish volume. The included wrist pins are 0.927 inches in diameter. Keep in mind these are not CARB approved and cannot be shipped to California. For serious performance builds, these pistons offer a well-built solution with features honed for racing.
