Wiseco RED Series Chevy Small Block 400 4.135in Bore 1.000in CH -27.00 CC Piston Set

If you're rebuilding a Chevrolet Small Block 400 and need pistons that can handle serious performance, this Wiseco RED Series set is a solid choice. These pistons are specifically designed for the 4.135-inch bore size and feature a 1.000-inch compression height, making them a direct fit for your engine build. The RED series stands for Race Engineered Design, meaning they're built from the ground up for the demands of racing and power adder applications.

What sets these pistons apart is their construction from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard. Wiseco machines these pistons in the USA, and they incorporate features like horizontal slot oiling in the pin bores to ensure the wrist pins stay well-lubricated, which is key for long service life. The dedicated forgings allow for an optimized, engine-specific strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, leading to less wear on both the skirts and the cylinder walls. You also get premium rings included with each set, so you won't have to source those separately.

An accumulator groove is also 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. If you're building a performance engine for drag racing, circle track, or any application where durability and strength are paramount, this set is built to perform.
