Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.140in Bore - Set of 8

What you get in this kit are eight forged pistons designed specifically for Chevrolet LS engines. These aren't just any pistons; they're part of Wiseco's RED Series, which stands for Race Engineered Design. This means they're built with the strength and durability needed for high-performance racing and engines with power adders, like turbochargers or superchargers. They're machined from 2618 aluminum, a material known for its tensile strength, which is crucial when you're pushing an engine hard.

Wiseco has put some smart details into these pistons to help them perform and last. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pins and the small end of the connecting rods well-lubricated, a key factor for long service life. The pistons themselves use dedicated forgings, allowing for a strutted design that maximizes strength while keeping the weight down. Plus, they come with an ArmorGlide skirt coating. This coating is there to reduce friction and noise from the piston skirts against the cylinder walls, which also helps cut down on wear. To make things even easier, each set includes premium rings, so you won't have to hunt for those separately. There's also an accumulator groove, which helps maintain consistent ring seal and power output.

These pistons are made in the USA and are intended for serious performance builds, from drag racing to circle track applications. Keep in mind that these are not CARB approved and cannot be shipped to California. For any engine build aiming for serious power and reliability, these Wiseco RED Series pistons are a solid choice.
