Wiseco RED Series Chevy Small Block 400 4.130in Bore 1.250in CH -15.00 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 Chevy Small Block 400 engines, offering the strength and precision needed for demanding builds. These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, making them a solid choice for racing and engines with power adders.

The RED Series pistons feature Race Engineered Design (RED) to give you a competitive edge. They include horizontal slot oiling in the pin bores to keep the wrist pin and small-end of the connecting rod well-lubricated, which is crucial for long service life in high-stress environments. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an accumulator groove to help maintain consistent ring seal and power delivery. Plus, each set comes with premium rings, so you don't have to source them separately. The ArmorGlide skirt coating further reduces friction and noise, while also helping to minimize wear on the piston skirt and cylinder wall.

This set includes eight pistons, each with a 4.130-inch bore, a 1.250-inch compression height, and a -15.00 CC dish. Please note that these pistons are not CARB approved and cannot be shipped to California.
