CP Piston BRS Chevy 405Ci Ascs 4.145 Bore 1.125 Ch 8CC Dome - Set Of 8 (MTO Non-Cancel)

Forged from high-strength aluminum alloy, these CP Pistons Billet Series pistons are built for serious performance applications. The 4.145-inch bore size and 1.125-inch compression height are specifically chosen to work with many popular Chevy V8 engine builds, aiming for around 405 cubic inches of displacement. The 8cc dome volume is designed to achieve a specific compression ratio when paired with the right cylinder heads and gasket thickness, a critical factor for optimizing power and efficiency in a performance engine.

These pistons feature an 8-ring groove design, which helps manage combustion pressures and oil control more effectively than a standard 5-ring setup. The skirt design incorporates lateral gas ports, an advanced feature that helps reduce ring land pressure and improve ring seal, especially under high-boost or high-RPM conditions. This attention to detail in the design helps ensure consistent performance and durability when you're pushing your engine hard. Each piston is meticulously machined to tight tolerances, ensuring a precise fit within the cylinder bore for optimal sealing and reduced friction.

This set includes eight pistons, enough for a complete V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always recommended to consult with your engine builder or a trusted performance shop to confirm compatibility with your specific engine combination and build goals. Proper installation and matching with other engine components are crucial for achieving the desired performance and longevity.
