Superior Sealing with Moly Performance Rings

For engines bored to 4.030 inches, the Sealed Power Moly Piston Ring Set offers an exceptional balance of durability and performance. These rings are engineered for enthusiasts who demand more from their engine, utilizing a moly-coated steel construction to minimize friction and maximize compression. The moly coating is specifically chosen for its ability to withstand high temperatures and provide a smoother surface for the piston to travel against.

Technical Specifications

  • Bore Size: 4.030 inches
  • Ring Thickness: 5/64 x 5/64 x 3/16 inch
  • Material: Steel with Moly Face
  • Tension: Standard Tension
  • Compatibility: 8-Cylinder Engines
  • Design: High-performance drop-in

By upgrading to these moly-filled rings, you ensure a tighter seal that helps prevent oil consumption and power-robbing blow-by. The steel construction provides the structural integrity needed for engines that see higher RPMs or increased load. These rings are designed to seat quickly and effectively, providing immediate performance gains upon installation. Perfect for engine rebuilds where precision and reliability are paramount, these rings represent the standard in modern engine sealing technology. Trust your engine build to the experts and find the right components for your project at GGCRACING.
