SBF FT Forged Piston Set 4.030 Bore -5.3cc

The ICON Pistons SBF FT Forged Piston Set 4.030 Bore -5.3cc is a premium forged piston assembly designed for small block Ford engines that require tight bore specifications and lower displacement characteristics. This set includes 8 pistons, delivering the strength and precision necessary for high-performance, street, and competition applications where reliability and consistent ring sealing are essential.

The -5.3cc dish design effectively reduces total engine displacement while maintaining structural integrity under sustained load. Each piston features a standard ring groove configuration of 1/16 x 1/16 x 3/16 inches, optimizing compression ring seating and oil control across a wide range of small block Ford applications. The 4.030-inch bore diameter accommodates overbored blocks, and the forged construction provides superior fatigue resistance compared to cast alternatives, especially in engines subjected to aggressive tuning or high RPM operation.

This piston set is ideal for small block Ford enthusiasts, engine builders, and restoration specialists who require OEM-compatible bore sizing with forged reliability. Whether replacing worn stock pistons or assembling a fresh long-block, this set meets the demands of street driving, bracket racing, or vintage hot rod restoration.
