Forged from high-strength 2618 aluminum alloy, these CP Pistons Bullet Race Series pistons are built for serious performance in Chevy LS2 engines. The 4.065-inch bore and 4.125-inch stroke are specifically chosen to work with a 6.125-inch connecting rod, creating a robust rotating assembly for demanding applications. This set includes eight pistons, designed to handle the stresses of high-horsepower builds.

CP Pistons is known for its well-built components, and this Bullet Race Series set is no exception. The 2618 alloy offers a good balance of strength and weight, crucial for engine longevity under load. The design focuses on reliability and performance, making them a solid choice for engine rebuilds where power and durability are key. Each piston in this set is precision-machined to ensure consistent performance and proper fitment within the cylinder bore.

When rebuilding your LS2 engine, choosing the right internal components is critical. These pistons are designed to be a direct replacement for the factory bore size, but they are intended for use with aftermarket connecting rods and a specific crankshaft stroke to achieve the desired displacement and compression ratio. Always consult your engine builder or a qualified mechanic to ensure these pistons are the correct choice for your specific build goals and to confirm all necessary supporting components, such as rings, pins, and bearings, are compatible and included in your build plan.
