Wiseco Chevy SB RED Series Piston Set 4130in Bore 1550in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine for racing or serious street use, a strong set of pistons is fundamental. The Wiseco RED Series pistons are forged from 2618 aluminum, a material chosen for its tensile strength, which is crucial when you're pushing an engine hard, especially with power adders like turbos or superchargers. These pistons are designed to handle the demands of drag racing and circle track applications, offering a solid foundation for your build.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're also precisely machined for a competitive edge. They feature horizontal slot oiling in the pin bores to ensure the wrist pin and small-end of the connecting rod stay well-lubricated, which is key for longevity under stress. 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, leading to less wear on the skirts and cylinder walls. Each set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. When planning your build, ensure you have the correct connecting rods and crankshaft to match the 4.130 inch bore, 1.550 inch compression height, and 0.927 inch pin diameter.
