Wacky-looking, simple and effective-all words that describe the new Super-Flex U-joint. Its unique design of offset trunnions sets the mating yokes farther apart than a conventional joint. Wood says that this allows for 10 degrees more flexibility than would be obtainable with a conventional joint. He notes that 10 degrees may not sound like a lot, but with a 30-inch driveshaft, this will allow more than 5 inches of additional droop at the axle prior to binding of the universal joint. His testing has shown that when this U-joint is installed in standard yokes, the driveshaft will flex to 40 degrees. With grinding, the driveshaft will flex to 45 degrees. The Super-Flex joint is available in 1310 and 1350 series.
