KB Hypereutectic Dished Pistons for SBC

Manage your compression ratio effectively with this set of KB Hypereutectic dished pistons, designed specifically for a 4.030-inch bore Small Block Chevy. These -28cc dished pistons are the ideal choice for forced induction builds or applications requiring a lower compression ratio to prevent detonation while running pump gas.

Performance Features

  • Bore Size: 4.030 inches
  • Piston Style: Dished (-28cc)
  • Ring Grooves: 1/16 x 1/16 x 3/16 inch
  • Material: High-Strength Hypereutectic Alloy
  • Set Includes: 8 Pistons

The use of a high-silicon hypereutectic alloy provides these pistons with excellent thermal stability and wear resistance. The -28cc dish design is engineered to provide the necessary combustion chamber volume for high-boost or high-compression engine configurations. By utilizing a 1/16 x 1/16 x 3/16 ring pack, these pistons promote improved ring seal and reduced friction, helping your engine achieve maximum efficiency and power output. These pistons are built to withstand the increased cylinder pressures associated with performance modifications, ensuring your engine remains reliable under load. Whether you are building a street-legal blower motor or a high-performance turbo setup, these pistons offer the durability and performance you need to succeed. Upgrade your engine's bottom end with premium components from GGCRACING.
