Precision Engineered KB Hypereutectic Pistons

Upgrade your Small Block Chevy with the reliability of KB Hypereutectic Flat Top Pistons. Specifically sized for a 4.040 bore, these pistons are the perfect choice for a bored-out block requiring a high-quality, durable solution. The -7cc dish design helps maintain optimal compression for improved throttle response and overall engine power.

Key Features and Benefits

  • Optimized for 4.040 inch bore SBC engines
