Wiseco RED Series Chevy Small Block 400 4.130in Bore 1.125in CH -21.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance racing and power adder applications. The RED (Race Engineered Design) series utilizes dedicated forgings that allow for an optimized, engine-specific strutted design, maximizing strength while keeping weight down. This is crucial for engines that see hard use, whether on the drag strip or the circle track.

Wiseco incorporates several features to ensure longevity and consistent performance. Horizontal slot oiling in the pin bores keeps the wrist pin and small-end of the connecting rod properly lubricated, which is vital for extended service life under high stress. An accumulator groove is included to help maintain consistent ring seal and power output. Each set also comes with premium rings, so you don't have to source them separately.

Additionally, the ArmorGlide skirt coating on these pistons helps reduce operating friction and noise, while also minimizing skirt and cylinder wear. This set is designed for Chevrolet Small Block 400 engines with a 4.130-inch bore and a 1.125-inch compression height, featuring a -21.00cc dish volume. Please note that these pistons are not CARB approved and cannot be shipped to California.
