CP Piston Bullet Race Series Chevy LS3 4.070 Bore 4.000 Stroke 6.125 Rod Set Of 8

This set includes eight CP Pistons Bullet Race Series pistons, designed for Chevy LS3 engines. These pistons feature a 4.070-inch bore, a 4.000-inch stroke, and are built to work with a 6.125-inch connecting rod. They are forged from high-strength aluminum, a common practice for performance pistons because it offers a good balance of strength and weight, which is crucial for high-RPM operation. The Bullet Race Series is a popular choice for builders looking to push the limits of their LS3 engines.

When you're rebuilding the top end of a high-performance engine like the LS3, the pistons are a critical component. These CP Pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them well-suited for the increased cylinder pressures and temperatures found in race or heavily modified street applications. The specific bore size of 4.070 inches is important for achieving the desired displacement when paired with the correct crankshaft and connecting rods. The 6.125-inch rod length is also a key dimension that affects piston pin height and overall engine geometry.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions to ensure proper fitment and assembly with your specific engine build. Proper ring gap setting and piston-to-wall clearance are essential for optimal performance and longevity.
