Wiseco Chevy LS1/LS2 RED Series Piston Set 3780in Bore 1304in Compression Height - Set of 8

If you're building a high-performance Chevy LS1 or LS2 engine, Wiseco's RED Series pistons are a solid choice. These pistons are forged from 2618 aluminum, a material known for its tensile strength, making them well-suited for demanding racing applications and engines that use power adders like superchargers or turbochargers. The RED Series name stands for Race Engineered Design, and these pistons are built with precision-machined features to give you a competitive edge on the track.

Wiseco machines these pistons in the USA, and they've incorporated several thoughtful details. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and the small end of the connecting rod properly lubricated, helping to ensure a long service life for these critical components. The dedicated forgings allow for an optimized, engine-specific strutted design, which helps maximize strength while keeping the weight down. Each set also comes with premium rings, so you won't need to source those separately.

To further reduce friction and noise, these pistons feature an ArmorGlide skirt coating. This coating also helps to minimize wear on both the piston skirt and the cylinder wall. An accumulator groove is included to help maintain consistent ring seal and consistent power delivery. Please note that these pistons are not CARB approved and cannot be shipped to California.
