CP Piston Bullet Race Series Chevy LS7 4.130 Bore 4.000 Stroke 6.125 Rod 1.120 Set Of 8

If you're building a high-performance Chevy LS7 engine, especially one destined for serious track duty or extreme street use, a strong set of pistons is fundamental. These CP Pistons Bullet Race Series pistons are forged from high-strength aluminum to handle the immense pressures and heat generated in a powerful LS7. They are specifically designed for the LS7's 4.130" bore, a 4.000" stroke, and utilize a 6.125" connecting rod with a 1.120" wrist pin diameter.

CP Pistons is known for making well-built internal engine components, and this Bullet Race Series set is no exception. The forged construction means these pistons are significantly stronger and more durable than cast pistons, making them ideal for applications where reliability under stress is paramount. The specific dimensions are critical for achieving the correct compression ratio and piston-to-wall clearance, which directly impacts engine performance, efficiency, and longevity. This set includes all eight pistons needed for a complete engine build.

When building a performance LS7, attention to detail is key. Ensure you have the correct ring set and wrist pins to complement these pistons, as they are often sold separately. Proper installation and balancing are crucial for optimal performance and to prevent premature wear. These pistons are not CARB approved and cannot be shipped to California.
