Wiseco RED Series Chevy Small Block 400 4.130in Bore 1.000in CH -27.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This RED Series piston set is built for the Chevrolet Small Block 400 engine, offering the kind of durability and precision needed for serious racing and power adder setups. These aren't your average pistons; they're designed to handle the demands of drag racing, circle track, and other high-performance environments.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard. To further enhance their performance and longevity, they feature horizontal slot oiling in the pin bores. This ensures your wrist pins and the small end of the connecting rods get consistent lubrication, which is vital for keeping things running smoothly under stress. The dedicated forgings allow for an engine-specific, strutted design that maximizes strength while keeping weight down, a key factor in overall engine performance.

You'll also find an accumulator groove designed to help maintain a consistent ring seal, which means better compression and more power. Plus, each set comes complete with premium rings, so you don't have to hunt for compatible ones separately. The ArmorGlide skirt coating is another notable feature, working to reduce friction and noise while also minimizing wear on the piston skirts and cylinder walls. This attention to detail helps ensure a long service life for your engine build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds where maximum durability and power are the primary goals.
