CP Piston Bullet Race Series Chevy LS1 3.905 Bore 3.622 Stroke 6.125 Rod Set Of 8

Forged from 2618 aluminum alloy, these CP Pistons Bullet Race Series pistons are built for high-performance Chevy LS1 engines. The 3.905-inch bore size, combined with a 3.622-inch stroke and a 6.125-inch rod length, creates a specific compression ratio and displacement tailored for racing applications. This set includes eight pistons, designed to handle the demands of serious engine builds where reliability and power are paramount.

The 2618 aluminum alloy offers a good balance of strength and thermal expansion, making it suitable for the high temperatures and pressures found in performance engines. CP Pistons uses a deep valve relief design to ensure proper clearance with larger camshafts and high-lift valve events, a common requirement in modified LS1 engines. Each piston in this set features a skirt coating to reduce friction and wear, contributing to improved engine efficiency and longevity under extreme conditions. The included wrist pins are also robust, designed to withstand significant lateral forces.

This piston set is intended for builders who are pushing the limits of their LS1 engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, professional installation and proper engine tuning are highly recommended. Ensure you consult with your engine builder or a qualified performance tuner to confirm compatibility with your specific camshaft, cylinder heads, and other engine components.
