CP Piston Bullet Race Series Chevy LS3 4.070 Bore 4.125 Stroke 6.125 Rod Set Of 8

CP Pistons Bullet Race Series forged pistons are built for high-performance Chevy LS3 engines. This set is designed for a 4.070 inch bore, a 4.125 inch stroke, and uses a 6.125 inch connecting rod. You get a complete set of 8 pistons, ready for your engine build.

These pistons are forged from high-strength aluminum alloy, a common choice for racing applications because it offers a good balance of durability and weight. The Bullet Race Series is known for its robust construction, intended to handle the stresses of demanding engine builds. The specific design features, like the skirt profile and pin boss reinforcement, are engineered to reduce friction and improve overall engine efficiency under high load conditions. This attention to detail helps ensure reliable performance when you're pushing your engine hard.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and ring gap settings, as these are critical for proper engine break-in and long-term reliability. Because these are performance pistons, they are often paired with aftermarket connecting rods and a performance crankshaft to achieve optimal results. Remember, this part is not CARB approved and cannot be shipped to California.
