High-Output Forged Pistons for SBC

Push your Small Block Chevy to the next level with the Speed Pro Forged Piston set. Engineered for durability and high-performance applications, these forged aluminum pistons are the ideal choice for engines that see heavy use or high-stress environments. The 4.040-inch bore size accommodates a .040 overbore, allowing you to clean up cylinder walls while increasing displacement for a slight power gain.

Performance Features

  • Material: Premium Forged Aluminum
  • Bore: 4.040 inches
  • Volume: -5.40 cc
  • Ring Grooves: 5/64 x 5/64 x 3/16 inch
  • Coating: Advanced skirt coating
  • Set: 8 Pistons included

These pistons feature a -5.40 cc dish, which helps manage compression ratios in performance builds. The inclusion of a specialized skirt coating is critical for high-performance engines, as it minimizes friction and prevents scuffing during the break-in process and under high-heat conditions. By choosing forged over cast, you are ensuring that your engine can handle the heat and pressure of aggressive driving. These pistons are the foundation of a reliable, high-horsepower engine build. Trust in the durability of Speed Pro for your next project. Get the best parts for your ride at GGCRACING.
