CP Piston Bullet Race Series Chevy LS3 4.080 Bore 3.622 Stroke 6.125 Rod Set Of 8

These CP Pistons Bullet Race Series pistons are forged from 2618-T61 aluminum, a strong material chosen for its ability to handle high cylinder pressures and temperatures found in performance LS3 builds. The 4.080-inch bore size is a common upgrade for LS3 engines looking to increase displacement, paired with a 3.622-inch stroke and a 6.125-inch rod length, this combination is designed for serious performance applications.

Each piston in this set of eight features a unique Bullet Race Series design, optimized for strength and weight. They come ready for a 0.015-inch undersize bore, meaning they are intended for engines that have been machined to a slightly smaller diameter than stock, allowing for a precise fit and proper clearance. This attention to detail in manufacturing helps ensure reliable performance under demanding conditions, whether you're building a track car or a high-performance street machine.

When rebuilding your LS3 engine with these pistons, ensure you have the correct supporting components. This includes appropriate piston rings, wrist pins, and connecting rods that match the 6.125-inch length specified. Proper balancing of the rotating assembly is also crucial for longevity and smooth operation at higher RPMs. Remember, these pistons are not CARB approved and cannot be shipped to California.
