Wiseco RED Series Chevrolet Big Block 4.320in Bore 1.645in CH 35.00 CC Piston Set

If you're rebuilding a performance Chevrolet Big Block engine, especially for demanding applications like drag racing or circle track, you need pistons that can handle serious stress. The Wiseco RED Series pistons are built for exactly that scenario. They utilize Race Engineered Design (RED) principles, meaning they're forged and machined in the USA from 2618 aluminum, chosen for its high tensile strength needed in racing and when using power adders.

Wiseco has put a lot of thought into the details here. The horizontal slot oiling in the pin bores is a smart touch, ensuring your wrist pins and the small end of the connecting rods stay well-lubricated, which is crucial for keeping these high-performance engines alive. These pistons use dedicated forgings, allowing for an optimized strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, and it also helps cut down on wear on both the piston skirt and the cylinder walls. You also get premium rings included with each set, so you won't have to hunt for those separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set is designed for a 4.320-inch bore and includes everything you need for an 8-cylinder engine. Keep in mind that these are not CARB approved and cannot be shipped to California. For serious builds, these pistons offer a well-built foundation.
