This Chevrolet Performance Piston Ring Set (12499231) is engineered for builders who demand reliability and consistent compression. Designed specifically for a 4.000-inch bore, these rings feature a low-tension configuration that minimizes friction while maximizing power output across the RPM range.

  • Ring Thickness: 2.0mm (Top), 1.5mm (Second), 4.0mm (Oil)
  • Application: 8-Cylinder Small Block Chevy
  • Type: Low Tension
  • Material: High-strength alloy for heat dissipation
