Wiseco RED Series Chevy Small Block 400 4.155in Bore 1.062in CH -24.00 CC Piston Set

This piston set from Wiseco gives you everything you need to rebuild the heart of your Chevy Small Block 400 engine. You get a complete set of eight forged pistons, each designed with Wiseco's Race Engineered Design (RED) philosophy to offer serious strength and durability for performance applications. These aren't just basic pistons; they're precision-machined from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of racing and boosted engines.

Wiseco has thought through the details that matter for long service life and consistent performance. The horizontal slot oiling in the pin bores ensures the wrist pins and connecting rod small ends stay well-lubricated, which is crucial under high stress. The pistons themselves feature a strutted design, optimized for the specific engine to maximize strength while keeping weight down. Plus, they come with an ArmorGlide skirt coating that helps reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. You also get premium rings included with each set, so you won't have to hunt for compatible ones separately. An accumulator groove is also built-in to help maintain consistent ring seal and keep power levels steady.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a performance Chevy Small Block 400, this set offers a well-built foundation with features aimed at durability and competitive performance.
