Wiseco RED Series Chevy LS 4.020in Bore 1.294in CH -15.00 CC Piston Set

If you're rebuilding a high-performance Chevy LS engine for racing, like drag or circle track, a strong set of pistons is crucial. The Wiseco RED Series pistons are built for exactly these kinds of demanding applications. They use a Race Engineered Design (RED) to give you the strength and durability needed for serious power, along with precision features that help you get a competitive edge.

These pistons are forged and machined right here in the USA from 2618 aluminum, which is known for its tensile strength, making them well-suited for performance racing and engines with power adders. Wiseco includes a few smart details to help with longevity and performance. Horizontal slot oiling in the pin bores ensures the wrist pin and small end of the connecting rod stay well-lubricated, which is key for long service life. The dedicated forgings allow for an engine-specific strutted design that maximizes strength while keeping weight down. Plus, each set comes with premium rings, so you won't need to source those separately.

To further reduce friction and wear, these pistons feature an ArmorGlide skirt coating. This not only helps quiet things down but also reduces wear on the piston skirt and cylinder wall. An accumulator groove is also included to help maintain consistent ring seal and power output. This set includes 8 pistons, enough for a full V8 engine build.
