Computer designed to achieve ultimate strength at minimum weight. JT combines leading-edge technology with top materials to produce the ultimate quality sprocket range with unbeatable value. Every sprocket meets or exceeds the highest possible quality standards. Sprockets are heat-treated and beadblasted to reduce material surface tension. Front sprockets made with top-quality Japanese C45 high carbon steel and SCM415 chromoly steel alloy. Steel rear sprockets made with top-quality Japanese C45 high carbon steel. Aluminum rear sprockets are made with high strength Austrian 7075 T-6 anodized aluminum. JT aluminum sprockets are about 30% lighter than a comparable steel equivalent, which reduces un-sprung rotating weight and improves performance. New lightweight front sprockets available for some applications. NOTES:. When installing sprockets which differ from the Orig. Equipment size, check for proper clearances before operating.
