Wiseco RED Series Chevy Small Block 350 4.040in Bore 1.000in CH -8.00 CC Piston Set

If you're building a performance Chevy Small Block 350, this Wiseco RED Series piston set is designed to handle the demands of racing and power adder applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see hard use, whether on the drag strip or the circle track. The 4.040-inch bore size is a common upgrade for the 350, allowing for increased displacement and potential power gains.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're also precisely machined for a competitive edge. You'll find horizontal slot oiling in the pin bores, which helps keep the wrist pin and connecting rod small end properly lubricated for better longevity. The dedicated forgings allow for an optimized, engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. An accumulator groove is also included to help maintain consistent ring seal and power output.

This set includes eight pistons, each ready to be installed. It also comes complete with premium rings, so you won't need to source those separately. 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.
