The CP-Carrillo Bullet Series is a forged 2618 aluminum piston set built for high output Chevy LS3 engine builds running naturally aspirated, nitrous, supercharged, or turbocharged power. Each flat-top piston has a 4.065 inch standard bore, a 1.110 inch compression height, and works with a 4.000 inch stroke and 6.125 inch rod for roughly 11.5:1 compression on 66cc 15 degree LS heads. The set includes 1.5mm gas-nitride steel top rings, 1.5mm Napier second rings, 3.0mm oil rings, and 0.927 inch wrist pins. A special skirt design reduces piston noise, and every piston is machined in the USA.
