SBM FT Forged Piston Set 4.030 Bore -5cc

The ICON PISTONS SBM FT Forged Piston Set 4.030 Bore -5cc is a premium forged piston set designed specifically for Small Block Mopar applications. Engine builders and performance enthusiasts will appreciate its precision and durability, especially at high RPMs. This set includes eight pistons, making it ideal for those looking to enhance engine performance.

Each piston features a 4.030-inch bore with -5cc dome geometry and ring grooves sized at 1/16 x 1/16 x 3/16 inches. The forged construction provides superior strength and thermal stability compared to cast alternatives, which is critical for high-boost applications or extended track sessions. The -5cc dome configuration slightly reduces displacement while raising the compression ratio, a common specification for performance builds.

This piston set is perfect for engine builders, restoration specialists, and performance shops preparing Small Block Mopar engines for racing or high-output street builds. The precise ring groove dimensions minimize blowby and maintain optimal ring tension, protecting cylinder walls and extending engine life. With this piston set, you can achieve increased horsepower without the need for larger displacement.
