Wiseco RED Series Chevy LS 4.070in Bore 1.105in CH -20.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components for performance applications. Their RED Series pistons are built using Race Engineered Design principles, meaning they're crafted for the demands of racing and serious performance builds. If you're working on a Chevy LS engine that needs to handle serious power, these pistons are a solid choice.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing the limits with performance racing or adding power adders. They feature horizontal slot oiling in the wrist pin bores to keep the wrist pins and the small end of the connecting rods well-lubricated, which is crucial for keeping things running smoothly over the long haul. Wiseco uses dedicated forgings for each engine application, allowing them to optimize the strutted design for maximum strength while keeping the weight down. Plus, each set comes with premium rings, so you don't have to hunt for those separately.

To further reduce friction and noise, these pistons have an ArmorGlide skirt coating. This not only helps with smoother operation but also cuts down on skirt and cylinder wear. An accumulator groove is also included, which helps maintain consistent ring seal and power delivery. Keep in mind these are not CARB approved and cannot be shipped to California.
