Improved durability, crack & wear-resistance provides up to 2x the life of the original G-Force Belt Proprietary Ethylene Elastomer (EE) compound creates improved axial stiffness and increased heat tolerance for higher loads, higher peak torque, less heat fade, and less speed loss High tensile aramid cord maximizes acceleration, shock load resistance, and extreme fatigue resistance; great for hauling heavy loads across aggressive terrain Not for use in turbocharged or heavily modified engine applications 1 7/32" x 41 3/4"
