About this part

Product Details

CP Pistons is well-known for making strong internal engine components for high-performance applications. This Bullet Race Series piston set is a prime example, built for Chevy LS3 engines that demand serious power. You're looking at a set of eight pistons, each precision-machined to a 4.075-inch bore size, designed to work with a 4.000-inch stroke and a 6.125-inch connecting rod. These aren't your average pistons; they're forged from high-strength aluminum to handle the extreme pressures and temperatures found in race-tuned or heavily modified LS3 engines.

The Bullet Race Series is engineered for durability and performance under demanding conditions. The 4.075-inch bore size is a common upgrade for increasing displacement in LS3 engines, allowing for more air and fuel to be processed, which translates to more power. The 6.125-inch rod length is a standard choice for many performance LS builds, balancing stroke length with piston speed and rod angle for improved efficiency and reduced stress. These pistons are designed to be a direct fit for the specified bore and stroke combination, making them a solid choice for engine builders looking to maximize the potential of their LS3.

When building a high-performance engine, the quality of internal components like pistons is critical. This set from CP Pistons offers the robust construction and precise dimensions needed to reliably put down serious horsepower. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to the manufacturer's installation guide for specific details regarding assembly and compatibility with other engine components.
