CP Piston BRS Chevy LS7 4.155 Bore 4.000 Stroke 6.125 Rod Dome Set Of 8 (MTO Non-Cancel)

These CP Pistons are forged from high-strength aluminum, specifically designed for the demanding requirements of a Chevy LS7 engine. The 4.155 inch bore and 4.000 inch stroke are key dimensions that define the engine's displacement and performance characteristics. This set includes pistons with a dome design, intended to work with specific cylinder head combustion chamber volumes to achieve a desired compression ratio. The 6.125 inch rod length is also a critical measurement, dictating the piston's stroke and its relationship with the crankshaft and connecting rod.

CP Pistons are well-known for their robust construction, utilizing advanced forging techniques to create pistons that can withstand high cylinder pressures and temperatures. This particular set is built for the LS7, a high-performance V8 engine, meaning these pistons are engineered to handle significant stress. The dome shape is a deliberate design choice that influences airflow within the combustion chamber and helps achieve a specific compression ratio, which is crucial for tuning engine performance. Because these are made-to-order, they offer a unique opportunity to get a precisely matched component for your build.

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 performance specialist to ensure these pistons are the correct choice for your specific engine build and to understand the full implications of the dome design on your target compression ratio and fuel requirements.
