Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.070in Bore - Set of 8

Wiseco is well-known for making strong, reliable forged pistons for performance applications. This RED Series piston set is built specifically for Chevrolet LS engines, designed to handle the demands of racing and boosted setups. These aren't your average pistons; they're crafted with precision to give your engine a competitive edge whether you're on the drag strip or the circle track.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for performance racing and when adding power adders like turbochargers or superchargers. To ensure optimal lubrication and extend service life, they feature horizontal slot oiling in the pin bores, keeping the wrist pin and connecting rod small end well-lubricated. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an accumulator groove to help maintain consistent ring seal and power, and an ArmorGlide skirt coating that reduces friction and noise while minimizing wear on the piston skirt and cylinder wall.

This set includes premium rings, so you won't need to source those separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine, these pistons are a solid option for durability and performance.
