When oval kart racer Jordan Stotts contacted us a few weeks back asking if the 3D clutch could withstand the abuse of a 500cc 80 horsepower sled engine, we thought he was joking and that it was some kind of prank call. After finding out that this was a serious request, our response was stiffer springs, beefier sprocket, and perfect alignment of the planets.

Despite our warnings, Jordan placed the order for the custom build and we put together a clutch for him with a #428 13 tooth sprocket, and 250 pound high temp stainless springs which increased the static torque rating from 25 to 50 foot pounds.
