Wiseco RED Series Chevy Small Block 400 4.125in Bore 1.000in CH -27.00 CC Piston Set

If you're building a high-performance Chevy Small Block 400 for the demands of racing, like drag or circle track, you need pistons that can handle serious stress. The Wiseco RED Series is built for just that, using Race Engineered Design principles to give you a competitive edge. These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines running high compression or forced induction.

Wiseco has put a lot of thought into the details that make a difference in durability and performance. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and small-end of the connecting rod well-lubricated, a key factor for long engine life under load. The dedicated forgings are shaped into an engine-specific strutted design, balancing strength with a low weight. Plus, the ArmorGlide skirt coating helps cut down on friction and noise, while also reducing wear on the piston skirt and cylinder wall. Each set comes complete with premium rings, so you won't have to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built, performance-oriented piston set for your Chevy Small Block 400 build, the Wiseco RED Series offers a strong option with features aimed at maximizing strength and longevity in demanding applications.
