Wiseco RED Series Chevrolet Big Block 4.500in Bore 1.155in CH 15.00 CC Piston Set

What you get in this box is a complete set of eight Wiseco RED Series pistons, designed specifically for Chevrolet Big Block engines with a 4.500-inch bore. These aren't just any pistons; they're built using Wiseco's Race Engineered Design (RED) process, which means they're forged and machined right here in the USA from strong 2618 aluminum. This material choice is crucial for handling the intense pressures and heat found in high-performance racing applications, especially those using power adders like turbos or superchargers.

Wiseco has thought through the details to make these pistons perform and last. You'll find horizontal slot oiling in the wrist pin bores, which is a smart way to keep the wrist pins and the connecting rod's small end well-lubricated, a key factor for long engine life under stress. The dedicated forgings allow for an optimized, engine-specific strutted design, meaning they've been shaped to give you the best possible strength without adding unnecessary weight. Plus, each set comes with premium rings, so you won't have to hunt for compatible ones. The ArmorGlide skirt coating is another notable feature, working to reduce friction and noise while also cutting down on wear to the piston skirts and cylinder walls. An accumulator groove is also included to help maintain consistent ring seal and ensure you're getting all the power your engine can make.

Because these are performance pistons, it's important to note they are not CARB approved and cannot be shipped to California. For any performance build, especially one involving a Chevrolet Big Block, these Wiseco RED Series pistons offer a well-built foundation for serious power.
