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

If you're building a high-performance Chevy LS2 engine, especially one destined for the track or serious street use, a strong set of pistons is fundamental. The CP Pistons Bullet Race Series pistons are built to handle the demands of boosted or naturally aspirated performance builds where reliability under stress is key. These pistons are designed for a 4.005 inch bore, a 4.000 inch stroke, and work with a 6.125 inch connecting rod, making them a solid choice for many LS2 performance applications.

CP Pistons uses a forged aluminum construction for this Bullet Race Series set. Forging the aluminum creates a stronger, more durable piston that can withstand higher cylinder pressures and temperatures compared to cast pistons. This is crucial for engines that will be pushed hard, whether that's with forced induction like turbochargers or superchargers, or simply a high-compression naturally aspirated setup. The specific bore size of 4.005 inches and the 4.000 inch stroke are common for many LS2 builds, and the 6.125 inch rod length is also a standard pairing, ensuring good compatibility with many performance crankshafts and connecting rods.

This set includes all eight pistons needed for a V8 engine, along with the necessary components for installation. When building a performance engine, attention to detail is everything, and starting with well-made pistons like these from CP Pistons sets a strong foundation for your build. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
