Wiseco RED Series Chevy Small Block 400 4.130in Bore 1.062in CH -24.00 CC Piston Set

If you're rebuilding a Chevrolet Small Block 400 and need pistons that can handle serious performance, this Wiseco RED Series set is built for the job. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for demanding racing applications and engines with power adders. The 4.130-inch bore size is specific to the Small Block 400, and each piston features a -24.00cc dish to help achieve your desired compression ratio.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're also precisely machined for a competitive edge. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and small-end of the connecting rod properly lubricated, extending their service life. The dedicated forgings allow for an optimized, engine-specific strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. This set comes complete with premium rings, so you won't need to source them separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set includes eight pistons, rings, and wrist pins, ready for installation in your Chevy Small Block 400. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
