Wiseco RED Series Chevy Small Block 400 4.155in Bore 1.550in 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 the Chevrolet Small Block 400 engine, offering the kind of durability and precision needed for serious performance builds, from drag racing to circle track. 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 when you're pushing an engine hard or adding forced induction.

What sets these RED Series pistons apart is their Race Engineered Design. You'll find features like horizontal slot oiling in the pin bores, which keeps the wrist pin and connecting rod small end well-lubricated for a longer service life. The dedicated forgings mean Wiseco can optimize the strutted design for each specific engine, maximizing strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and it also cuts down on wear to the piston skirt and cylinder wall. This set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

This set includes eight pistons, designed for a 4.155-inch bore with a 1.550-inch compression height and a -15.00cc dish volume. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
