Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.035in Bore - Set of 8

When you're building a performance Chevrolet LS engine, you need parts that can handle the stress. This set of eight Wiseco RED Series pistons is built for just that. They're designed with a flat top profile, a 4.035-inch bore, and are intended for a 4.000-inch stroke, making them a solid choice for serious engine builds.

Wiseco makes these pistons from 2618 aluminum, a material known for its strength, which is crucial for racing and engines with power adders. They've also incorporated some smart design features to help them last. The horizontal slot oiling in the pin bores keeps the wrist pins and connecting rod small ends well-lubricated, which is key for durability. Plus, each set comes with premium rings already included, so you don't have to hunt for those separately. The ArmorGlide skirt coating is there to reduce friction and noise, and also helps cut down on wear on the piston skirts and cylinder walls. An accumulator groove is also part of the design, helping to maintain a consistent seal for the piston rings and keep power delivery smooth.

These pistons are made in the USA and are specifically engineered for LS engines, using dedicated forgings that are shaped to maximize strength while keeping weight down. Keep in mind that these are not CARB approved and cannot be shipped to California.
