Wiseco RED Series Chevrolet Small Block 4.130in Bore 1.250in CH -1.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components for performance applications. Their RED Series pistons are built using Race Engineered Design principles to give your Chevrolet Small Block engine the strength and durability it needs, along with precision features that help you gain a competitive edge. These piston kits are a cornerstone for performance builds, whether you're hitting the drag strip or the 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 essential for racing and when you're adding power adders like turbochargers or superchargers. To help ensure long service life, they feature horizontal slot oiling in the pin bores, keeping the wrist pin and the small end of the connecting rod properly lubricated. The dedicated forgings allow for an engine-specific strutted design, which maximizes strength while keeping the weight down. You'll also find an accumulator groove that helps maintain consistent ring seal and power delivery. Plus, each set comes complete with premium rings, so you won't need to source those separately.

The ArmorGlide skirt coating on these pistons is designed to reduce operating friction and noise. It also helps to minimize wear on both the piston skirt and the cylinder wall, contributing to a longer engine life. This set is for a 4.130 inch bore with a -1.00 CC dish, and includes a 0.927 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
