Build a Better LS Engine with a United Engine and Machine Speed of Air Hyperformance Piston and Ring Kit

What if we told you that it’s possible for your LS engine to make more power while using less fuel and creating fewer emissions? United Engine and Machine’s Speed of Air Hyperformance Piston and Ring Kits can do just that.

The forged pistons feature patented technology from Speed of Air Engine Technologies that helps make internal combustion engines—from V-twin motorcycle to giant marine diesels—more efficient.

The Hyperformance piston crowns have machined dimples and a Cerakote thermal barrier ceramic coating. Together, they create a turbulent boundary layer between the combustion chamber walls and the incoming air/fuel mixture with accompanying flame front. This boundary forces the flame front to get much closer to the cooler combustion chamber, creating a lean burn condition that greatly improves combustion efficiency.

The benefits are impressive:
• Substantial increases in horsepower and torque
• Increase in fuel economy of up to 20% due to more efficient fuel burning
• Reduced NOx, CO2, and hydrocarbon emissions
• Increased engine life
• Less carbon buildup allows for extended oil change intervals

United Engine and Machine’s Speed of Air Hyperformance Piston and Ring Kits for GM LS are available to build 5.3L engines as well as 6.6L and 6.8L stroker combinations. They include a ring set with either chromium nitride-coated stainless steel or steel top rings, phosphate-coated ductile iron secondary rings, and chrome-faced stainless steel oil control rings. Wristpins and retainers are also included.
