This meticulous engineering translates directly into increased horsepower and torque output.
Each ring in this set is constructed from high-grade ductile iron, fortified with a plasma moly coating. This advanced material combination provides exceptional resistance to wear, heat, and friction, ensuring long-lasting durability and consistent performance under the most demanding conditions. The 1/16" (top), 1/16" (second), and 3/16" (oil) thickness profile, combined with a low-tension design, optimizes sealing efficiency while minimizing parasitic drag.
When uncompromising performance is your goal, Speed Pro delivers. These piston rings are a fundamental component for any serious engine build. Find all your high-performance engine parts at GGCRACING.COM.
