CP Piston BRS Chevy 403Ci All LS Bore 4.075 Stroke 4.000 Rod 6.125 Set Of 8 (MTO Non-Cancel)

Forged from 2618-T61 aluminum, these CP Pistons are built for serious performance in Chevy LS engines. The 4.075-inch bore and 4.000-inch stroke create a 403 cubic inch displacement, a popular choice for builders looking for a significant power increase over stock. The 6.125-inch rod length is a common specification that works well with many crankshafts and offers a good balance of stroke and piston speed for high-RPM operation.

CP Pistons uses a proprietary forging process that results in a strong, lightweight piston. This is crucial for engines that will see high cylinder pressures and temperatures, whether from forced induction or high compression naturally aspirated builds. The material choice and forging method contribute to excellent thermal stability and resistance to detonation. These pistons are designed to fit all LS-based engines, making them a versatile option for a wide range of performance applications. Because they are made to order, you can be confident you're getting a fresh set built specifically for your project.

This set includes eight pistons, rings, wrist pins, and locks, ready for installation. Please note that these pistons are not CARB approved and cannot be shipped to California. Due to their custom-made nature, orders for this piston set are non-cancelable once placed.
