BBM FHR Forged Piston Set 4.350 Bore -5.6cc

The ICON PISTONS BBM FHR Forged Piston Set 4.350 Bore -5.6cc is designed for serious engine builders and competition mechanics who prioritize durability and performance. This piston set is ideal for high-RPM applications, particularly in street performance engines, racing platforms, or boosted setups where traditional cast pistons may fail under extreme conditions.

Manufactured from aerospace-grade aluminum alloy, the BBM FHR pistons feature advanced ring groove designs that enhance ring seal and minimize blowby. The -5.6cc dish cavity effectively lowers the compression ratio, making these pistons suitable for high-octane tuning and forced induction applications. Their forged construction provides a superior strength-to-weight ratio, allowing for higher RPMs with reduced risk of failure.

Engine builders and tuners will appreciate the full-floating ring design, which reduces wear and extends service life under extreme conditions. This piston set is purpose-built for those looking to maximize performance and reliability in demanding environments, ensuring consistent compression sealing throughout the engine's operational range.
