Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.170in 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. They feature a flat-top design with a 4.170-inch bore and are intended for a 4.000-inch stroke, making them a solid choice for rebuilding or upgrading your LS powerplant.

These pistons are forged in the USA from 2618 aluminum, a material chosen for its excellent tensile strength, which is crucial when you're pushing an engine hard. Wiseco engineers these with dedicated forgings for an optimized strutted design, balancing strength with a manageable weight. You'll find horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends well-lubricated, which is key for long service life. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. An accumulator groove is also included to help maintain consistent ring seal and overall power output.

This set comes complete with premium rings, so you won't need to source those separately. Keep in mind these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
