High-Performance Sealed Power Hypereutectic Piston

Engine builders trust the Sealed Power Hypereutectic Piston for its exceptional strength and thermal stability. Designed specifically for Small Block Chevy applications, this 4.030-inch bore piston is engineered to handle increased cylinder pressures while maintaining tight tolerances. The hypereutectic alloy construction offers superior resistance to scuffing and heat, making it an ideal choice for street-strip performance engines.

Key Technical Specifications

  • Bore Size: 4.030 inches
  • Ring Grooves: 5/64 x 5/64 x 3/16 inch
  • Compression Ratio: -5.00 cc volume
  • Skirt Design: Coated for reduced friction and improved break-in
  • Material: High-strength hypereutectic aluminum alloy

The precision-machined ring grooves ensure optimal ring seal, reducing blow-by and maximizing power output throughout the RPM range. The coated skirt provides an extra layer of protection during initial startup and under high-load conditions, ensuring long-term reliability for your engine build. Whether you are performing a standard rebuild or a performance upgrade, these pistons deliver the consistency required for professional results. Trust GGCRACING for all your engine component needs.
