Wiseco Chevy SB RED Series Piston Set 4125in Bore 1550in Compression Height 0927in Pin - Set of 8

If you're building a performance Chevy Small Block V8, this Wiseco RED Series piston set is a solid choice. These pistons are forged from 2618 aluminum, a material known for its tensile strength, making them well-suited for the demands of racing and boosted applications. The RED series stands for Race Engineered Design, meaning Wiseco has optimized these pistons specifically for performance engines, aiming to give you a competitive edge.

Wiseco machines these pistons in the USA, and they come with some thoughtful features. The horizontal slot oiling in the pin bores helps keep the wrist pin and small end of the connecting rod properly lubricated, which is crucial for long service life in a high-stress engine. They also feature dedicated forgings for an optimized, engine-specific strutted design that balances strength with weight. To further reduce friction and wear, the skirts are coated with ArmorGlide, which also helps quiet things down. You'll also find an accumulator groove, designed to help maintain consistent ring seal and power delivery. This set includes premium rings, so you won't need to source those separately.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance V8 platforms commonly found in drag racing and circle track applications.
