Wiseco RED Series Chevy Small Block 350 4.040in Bore 1.250in CH -11.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance racing and engines with power adders. The 2618 alloy offers the tensile strength needed to handle the stresses of high-RPM operation and significant cylinder pressure, making them a solid choice for drag racing, circle track, and other demanding applications where durability is key.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just generic blanks; they utilize dedicated forgings optimized for specific engines like the Chevy Small Block 350. This allows for a strutted design that maximizes strength while keeping weight down. You'll also find horizontal slot oiling in the pin bores, a detail that ensures the wrist pin and small-end of the connecting rod stay well-lubricated, which is critical for long service life. The accumulator groove helps maintain consistent ring seal, contributing to reliable power delivery.

Each set comes complete with premium rings, so you won't need to source those separately. Additionally, the ArmorGlide skirt coating is applied to reduce operating friction and noise, while also minimizing wear on the piston skirt and cylinder wall. These pistons are designed for a 4.040-inch bore with a 1.250-inch compression height and a -11.00cc dish volume, suitable for many performance builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
