Wiseco RED Series Chevy Small Block 400 4.130in Bore 1.425in CH -21.00 CC Piston Set

When you're rebuilding a performance Chevrolet Small Block 400, the pistons are a critical component that needs to handle serious stress. The Wiseco RED Series pistons are built for this exact scenario, offering a robust solution for drag racing, circle track, and other demanding applications. These aren't just standard replacement parts; they're designed with Race Engineered Design (RED) principles to give you a competitive edge.

Crafted from 2618 aluminum in the USA, these pistons are forged for exceptional tensile strength, which is essential for engines running high compression or forced induction. Wiseco incorporates horizontal slot oiling in the pin bores to ensure the wrist pin and small-end of the connecting rod stay well-lubricated, a key factor for longevity in high-performance builds. The dedicated forgings allow for an optimized, strutted design that maximizes strength while keeping weight down. Plus, each set comes complete with premium rings, so you don't have to source them separately. An accumulator groove is also included to help maintain consistent ring seal and power delivery.

To further reduce friction and wear, these pistons feature an ArmorGlide skirt coating. This not only helps quiet down operation but also minimizes skirt and cylinder wall wear. If you're looking for a well-built piston set that's engineered for the rigors of performance racing, the Wiseco RED Series is a solid option. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
