Wiseco RED Series Chevy LS 4.065in Bore 1.105in CH -20.00 CC Piston Set

When you're building a high-performance Chevy LS engine, you need parts that can handle the stress. This piston set from Wiseco's RED Series is designed for just that. You get a complete set of eight pistons, each forged from 2618 aluminum for the tensile strength required in demanding racing and power-adder applications. They're engineered and machined right here in the USA, with dedicated forgings that allow for an optimized, engine-specific strutted design to maximize strength while keeping weight down.

Wiseco has included some smart features to help ensure longevity and consistent performance. The horizontal slot oiling in the pin bores keeps the wrist pin and small-end of the connecting rod well-lubricated, which is crucial for long service life under high loads. You'll also find an accumulator groove that helps maintain consistent ring seal and power delivery. Plus, each set comes with premium rings, so you won't need to source those separately. The ArmorGlide skirt coating is another notable detail, working to reduce operating friction and noise while also minimizing skirt and cylinder wear.

This set is specifically for a 4.065-inch bore with a 1.105-inch compression height and a -20.00cc dish volume. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're serious about building a powerful LS engine, this set offers a well-built foundation.
