CP Piston BRS Chevy LS2 4.040 Bore 3.622 Stroke 6.125 Rod 9.2 Set Of 8 (MTO Non-Cancel)

If you're building a high-performance Chevy LS2 engine, getting the right pistons is crucial for power and reliability. This set from CP Pistons is built for serious builds, offering a 4.040-inch bore and a 3.622-inch stroke, designed to work with a 6.125-inch rod. These are forged pistons, which means they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast ones, able to handle the higher cylinder pressures and temperatures found in modified or racing engines.

CP Pistons is known for making well-built internal engine components, and this BRS series set is no exception. The specific design details, like the 4.040-inch bore and 3.622-inch stroke, are chosen to optimize performance for the LS2 platform, often paired with specific crankshafts and connecting rods to achieve desired displacement and compression ratios. The 6.125-inch rod length is a common specification that balances stroke and piston compression height for many LS engine builds. This set includes eight pistons, enough for a full V8 engine.

Because these pistons are made-to-order (MTO) and non-cancelable, it's important to be sure they are the correct specification for your build before ordering. They are not CARB approved and cannot be shipped to California. Ensure these dimensions match your engine blueprint and intended build goals for a successful high-performance engine assembly.
