Wiseco Chevy SB RED Series Piston Set 4020in Bore 1250in Compression Height 0927in Pin - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance and racing engines. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined to give you an edge, whether you're on the drag strip or the circle track. This set is designed for popular domestic V8 platforms, forming the core of many high-performance builds.

Wiseco engineers these pistons with specific engine applications in mind, using dedicated forgings that optimize the strength-to-weight ratio. You'll find horizontal slot oiling in the wrist pin bores, which is crucial for keeping the wrist pin and small-end of the connecting rod properly lubricated, extending their service life. Each set also comes with premium rings, so you don't have to hunt for compatible ones. An accumulator groove is included to help maintain consistent ring seal and ensure you're getting all the power your engine can make.

The ArmorGlide skirt coating on these pistons plays a key role in reducing friction and noise during operation. This not only contributes to a smoother running engine but also helps minimize wear on both the piston skirt and the cylinder wall. This attention to detail in materials and design makes this set a solid choice for anyone rebuilding a performance Chevrolet Small Block engine.
