SBF FT Piston Set 4.030 Bore -5cc

The Race Tec Pistons SBF FT Piston Set 4.030 Bore -5cc is designed for small-block Ford engine builders seeking significant performance enhancements. This piston set is ideal for those rebuilding classic muscle cars, preparing street engines for boost, or assembling high-performance track engines.

Engineered with a 4.030-inch bore and a -5cc dish, these forged aluminum pistons are optimized for compression ratio tuning and provide reliable dome clearance in ported cylinder heads. The negative-dome design enhances compression while accommodating aggressive valve overlap and late intake valve closing events typical in high-lift cam profiles. The precision machining of ring grooves and piston-pin bosses ensures optimal ring seal and minimizes blow-by during combustion.

Serious builders and engine shops favor this SBF FT piston set for applications requiring reliability above 6,500 RPM, including stroker and turbocharged builds. Its robust construction and design make it a reliable choice for any small-block Ford platform aiming for high performance.
