C12 by Gates is an extreme-performance Neoprene (CR) belt which offers Original Equipment technology featuring trapezoid top-notch and rounded cog design for superior flexibility and heat disation. Carbon Cord belts are engineered for drop-in performance utilizing the strongest material on earth for tensile cord. Combined with a specially formulated adhesion gum, edge cord pullout is virtually non-existent.Carbon Tensile Cord ensures the belt maintains its designed length and geometrySuperior resistance to edge cord pull outUnique attributes of the Carbon Cord decreases the chance of edge cord pull outLess likely to damage clutches during belt failureEnhanced long term performanceImproved durability over AramidMinimal to no stretch under load creates optimal power transmissionImproved response during accelerationConsistent shift characteristics over time and through complete shift ratioUn-paralleled response during high load accelerationList of part numbers that are compatible with
