The Icon Pistons IC545C.STD is a high-performance forged piston set designed specifically for GM LS 5.3L engines with a 3.780-inch bore diameter. Manufactured from premium 2618 aluminum alloy, these forged pistons deliver exceptional strength and durability for demanding performance applications.

Key Features:

• Forged 2618 aluminum construction for superior strength-to-weight ratio
• 3.780-inch bore diameter (standard size) for LS 5.3L applications
• Flat-top (FT) design optimizes compression and combustion efficiency
• Precision-machined ring grooves and pin bores for accurate fitment
• Includes pistons, rings, pins, and locks for complete installation
• Designed to handle high RPM and boost applications
• Anti-friction skirt coating reduces friction and wear

Icon forged pistons are engineered to provide the reliability and performance needed for street/strip builds, forced induction setups, and high-output naturally aspirated LS engines. The flat-top design works well with factory or aftermarket cylinder heads to achieve optimal compression ratios for your specific combination.
