Wiseco RED Series Chevy Big Block 4.125in Bore 1.765in CH 42.00 CC Piston Set

If you're building a high-performance Chevy Big Block engine, Wiseco's RED Series pistons are a solid choice. These aren't your average pistons; they're forged from 2618 aluminum, a material known for its tensile strength, making them well-suited for the demands of racing and boosted applications. The Race Engineered Design (RED) philosophy behind these pistons means they're not just strong, but also precisely machined to give you an edge on the track or strip.

Wiseco has thought through the details that matter for longevity and performance. The horizontal slot oiling in the pin bores ensures your wrist pins stay well-lubricated, which is crucial for keeping things running smoothly over time. Each piston features a dedicated forging with a strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the skirts and cylinder walls. 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 4.125-inch bore and includes an accumulator groove to help maintain consistent ring seal and power delivery. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for 8-cylinder engines and are a cornerstone for performance builds from drag racing to circle track applications.
