Wiseco RED Series Chevy Small Block 350 4.040in Bore 1.125in CH -2.00 CC Piston Set

Wiseco is well-known for its high-performance forged pistons, and their RED Series takes that reputation a step further. These pistons are built using Race Engineered Design (RED) principles, meaning they're forged and machined in the USA from strong 2618 aluminum to handle the demands of racing and power adder applications. If you're building a Chevy Small Block 350 for serious performance, these pistons are designed to give you a competitive edge.

What sets these RED Series pistons apart is their attention to detail. They feature horizontal slot oiling in the pin bores to ensure your wrist pins and small-end connecting rod bearings stay well-lubricated, which is crucial for long service life under high stress. The dedicated forgings allow for an optimized, engine-specific strutted design, maximizing strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. Each set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set is specifically for a 4.040-inch bore with a 1.125-inch compression height and includes a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
