CP Piston Bullet Race Series Chevy LS2 4.005 Bore 4.000 Stroke 6.125 Rod Set Of 8

This set includes eight CP Pistons Bullet Race Series pistons, designed for Chevy LS2 engines. These pistons feature a 4.005-inch bore and are built to work with a 4.000-inch stroke crankshaft and 6.125-inch connecting rods. They are a popular choice for builders looking to assemble a high-performance engine that can handle significant power.

CP Pistons is known for its well-built forged pistons, and this Bullet Race Series is no exception. Forged from high-strength aluminum alloy, these pistons are built to withstand the extreme pressures and temperatures found in performance applications. The 4.005-inch bore size is specific for certain LS2 engine builds, often used when a slight overbore is part of the plan to refresh or increase displacement. The 6.125-inch rod length is a common specification for many performance LS engine builds, ensuring proper piston-to-deck height and compression ratio when paired with the correct crankshaft stroke and head gasket thickness.

When building a performance engine, attention to detail is crucial. These pistons are designed for a specific application, and it's important to ensure they match your intended crankshaft, connecting rods, and cylinder heads for optimal performance and reliability. Always consult your engine builder or the manufacturer's specifications to confirm all component compatibility before installation.
