SBC FT Piston Set 4.040 Bore -5cc

The SBC FT Piston Set 4.040 Bore -5cc from Race Tec Pistons is designed for small-block Chevrolet builds that require precision and durability in high-performance applications. This piston set is particularly suited for enthusiasts building stroker engines or competition-ready powerplants that demand tight tolerances and reliable dome geometry.

The -5cc combustion chamber volume enhances compression ratios while maintaining detonation control in boost or high-RPM environments. Made from premium forged aluminum alloy, these pistons feature advanced ring groove designs that promote consistent oil control and reduced blowby across the RPM range. The 4.040-inch bore specification is ideal for overbored short-blocks seeking added displacement and power output.

Mechanics and engine builders restoring or upgrading SBC platforms will appreciate the fitment precision and repeatable quality Race Tec delivers across each set. The strengthened pin bosses are designed to withstand repeated high-load cycles typical of street and strip applications. Proper ring gap setup and honing are essential for installation to ensure optimal performance.
