SBC Forged FT Piston Set 4.165 Bore -4.3cc

The JE PISTONS SBC Forged FT Piston Set 4.165 Bore -4.3cc is designed for small-block Chevrolet engine builders who demand high-performance and reliability. This piston set is ideal for street machines, weekend racers, or competition engines, providing the forged strength necessary to withstand extreme conditions.

Constructed from forged aluminum, these pistons are engineered to absorb thermal shock and resist cracking under high combustion pressures. The -4.3cc dish configuration offers controlled compression characteristics suitable for both forced-induction and naturally aspirated setups, ensuring optimal performance with pump gas or race fuel.

This piston set is compatible with small-block Chevrolet engines ranging from 283 to 400 cubic inches, depending on stroke and block configuration. By reducing rotating mass compared to heavier OEM units, these pistons enhance throttle response and minimize parasitic losses at high RPM, making them an excellent choice for performance enthusiasts.
