It was engineered to meet the demands of high horsepower diesel performance market. G3™ clutches: Higher torque capacity Improved shift - less noise and lower vibration (NVH) Consistent performance despite vehicle use and driver style Higher Energy capacity Reduced clutch burn out Red Eagle Friction is the go-to material for most performance applications. The lining has a unique dual saturation, which imparts high friction coefficients and high heat resistance. Red Eagle clutches are designed to limit the amount of "slip" by providing a shorter lock-up time, generating less heat. Red Eagle clutches: Are designed with a softer, more resilient base paper.
