Wiseco RED Series Chevy Small Block 350 4.000in Bore 1.000in CH -23.00 CC Piston Set

If you're rebuilding the heart of your performance Chevy Small Block 350, especially for demanding applications like drag racing or circle track, a solid set of pistons is crucial. This Wiseco RED Series piston set is built to handle the stress and heat that comes with serious engine work. They're designed to give you a competitive edge by combining robust strength with precision machining.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing your engine hard or adding power adders. Wiseco engineers each piston with dedicated forgings for an optimized, strutted design that maximizes strength while keeping weight down. You'll also find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pin and small-end of the connecting rod properly lubricated, helping to ensure a long service life. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, and it also cuts down on skirt and cylinder wear.

This set includes premium rings, so you won't have to hunt for compatible ones separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For a performance build where durability and precision matter, this Wiseco set is a well-built choice.
